An object is thrown straight down with an initial speed of 4 m/s from a window which is 8 m above the ground. Calculate: a) The time it takes the object to reach the ground b) Its velocity when it reaches the ground.
Answer:
0.41s
8.01m/s
Explanation:
Using the formula; v = u + at
Where;
u = initial velocity (m/s)
v = final velocity (m/s)
t = time (s)
a = acceleration (m/s²)
According to the provided information, u = 4m/s, s = 8m,
V = u + at
4 = 0 + 9.8t
4 = 9.8t
t = 0.41s
b) v = u + at
v = 4 + 9.8(0.41)
v = 4 + 4.018
v = 8.018m/s
A white dwarf star has a density of about 1.0 x 10^9 kg/m3. If the earth were to suddenly become as dense as a white dwarf star, what would its radius be?
Answer:
R = 98304.75 m = 98.3 km
Explanation:
The density of an object is given as the ratio between the mass of that object and the volume occupied by that object.
Density = Mass/Volume
Now, it is given that the density of Earth has become:
Density = 1 x 10⁹ kg/m³
Mass = Mass of Earth (Constant) = 5.97 x 10²⁴ kg
Volume = 4/3πR³ (Volume of Sphere)
R = Radius of Earth = ?
Therefore,
1 x 10⁹ kg/m³ = (5.97 x 10²⁴ kg)/[4/3πR³]
4/3πR³ = (5.97 x 10²⁴ kg)/(1 x 10⁹ kg/m³)
R³ = (3/4)(5.97 x 10¹⁵ m³)/π
R = ∛[0.95 x 10¹⁵ m³]
R = 98304.75 m = 98.3 km

How might you determine experimentally the moment of inertia of an irregularly shaped body about a given axis?
Answer:
Using the parallel axis theorem
Explanation:
We note the angular speed and also the systems energy. Using these information we calculate the moment of inertia of irregular shaped body.
Io = 2E/w²
When we have moment of inertia of irregular shaped body, we can then use parallel axis theorem to solve for the moment of inertia of the body about the given axis.
I = Io + md²
A 1000kg car is moving with a speed of 20m/s. Determine the net work required to move the
vehicle to a speed of 30m/s?
Answer:
250,000 Joules
Explanation:
The work required is the amount of energy added, so the answer is the difference in kinetic energy before and after the acceleration of the car. (The problem doesn't say it's flat where the car is, but well assume it since there is no information about an elevation change that would require us to concern ourselves with potential energy!)
W = E_final - E_initial
= 1/2 m v_final^2 - 1/2 m v_initial^2
= 1/2 m (v_final^2 - v_initial^2)
= 1/2 (1000 kg) ( (30 m/s)^2 - (20 m/s^2) )
= 1/2 (1000 kg) (500 m^2/s^2)
= 250,000 kg m^2/s^2
= 250,000 Joules

Complete abstinence is the best choice to prevent the consequences of sexual activity because this prevents any type of sexual contact and STDs.
What is Abstinence?Abstinence is a self-enforced restraint from the indulging in bodily activities which are widely experienced as giving pleasure to people. Most frequently, abstinence refers to sexual abstinence, however it can also mean abstinence from alcohol, drugs, food, etc.
Complete abstinence is the only way which can guarantee protection against the infection with sexually transmitted diseases. This means avoiding all the types of intimate genital contact. Someone who is practicing complete abstinence does not have any type of intimate sexual contact. So, there is no risk of getting an STD.

How high will a cannonball reach if fired straight up out of a cannon at an initial upward velocity of
120m/s?
Answer:
720 m
Explanation:
Taking the upward direction as positive
We are given:
Initial vertical velocity of the cannonball = 120 m/s
Vertical acceleration of the cannonball = -10 m/s²
Final velocity of the Cannonball = 0 m/s [at the maximum height, the velocity of the ball will be 0 m/s for a moment]
Maximum height of the ball:
v² - u² = 2as [Third equation of motion]
replacing the variables (s is the maximum height)
(0)² - (120)² = 2(-10)(s)
-14400 = -20s
s = -14400 / -20 [Dividing both sides by -20]
s = 720 m
Hence, the maximum height of the Cannonball fired vertically at a velocity of 120 m/s is 720 m
About how much greater is the gravitational force exerted by the moon on the near side of the earth than on the far side? Choose one of the Following:
(a) About 2% greater
(b) About 7% greater
(c) About 11% greater
(d) About 15% greater
Solution :
Distance between the Earth and the moon, D = [tex]$3.84 \times 10^8 \ m$[/tex]
Radius of the earth, r = [tex]$6.37 \times 10^6 \ m$[/tex]
Gravitational force on the near side of the moon, [tex]$F_N = \frac{GM_m m}{(D-r)^2}$[/tex] ......(1)
Gravitational force on the far side of the moon, [tex]$F_F = \frac{GM_m m}{(D+r)^2}$[/tex] ..............(2)
where, [tex]$M_m$[/tex] = mass of moon
m = mass of the near side and far side respectively (both are taken as equal)
Therefore,
[tex]$\frac{F_N-F_F}{F_N}\times 100 = \frac{\frac{GM_m m}{D-r}^2-\frac{GM_m m}{D+r}^2}{\frac{GM_m m}{D-r}^2} \times 100 $[/tex]
[tex]$=1 - \frac{(D-r)^2}{(D+r)^2} \times 100$[/tex]
[tex]$=1- \left(\frac{1-\frac{r}{D}}{1+\frac{r}{D}}\right)^2 \times 100$[/tex]
[tex]$= 1- \left(\frac{0.98}{1.02}\right)^2 \times 100$[/tex]
= 7%
Hence, correct option is (b) About 7% greater

A ball of clay is moving at a speed of 12 m/s collides and sticks to a stationary ball of clay. If each ball has a mass of 13 kg, what's the combined velocity of the two balls of clay after the collision
Answer:
p_{f} = 6 m / s
Explanation:
We can solve this exercise using conservation of momentum. For this we define a system formed by the two balls, so that the forces during the collision have been intense and the moment is preserved
Initial instant. Before the crash
p₀ = m v +0
Final moment. Right after the crash
[tex]p_{f}[/tex] = (m + m) v_{f}
how the moment is preserved
p₀ = p_{f}
m v = 2 m v_{f}
v_{f} = v / 2
we calculate
v_{f} = 12/2
p_{f} = 6 m / s
Why do you think the objects in each collision experience a different change in velocity?
Answer:
In a collision, there is a collision force which endures for some amount of time to cause an impulse. This impulse acts upon the object to change its velocity and thus its momentum

The mass of the reactants in the beginning of the reaction is 32g. What does the mass have to be in the end of the reaction in order to follow the law of conservation of mass?
Answer:
It has to be 32g
Explanation:
Mass at the beginning of the reaction is 32g
To ensure the law of conservation of mass, the mass at the beginning and end of the reaction must be the same.
The law of conservation of mass states that "matter is neither created nor destroyed but atoms combines with one another" .
So, if a reaction starts with 32g it must end with 32gWhat total distance did this student travel?
