She wants to travel back to Madison by train. The distance from Chicago to Madison is 147 miles and takes 2.47 hours. If she makes no stops, what is her average speed?
Answer:
59.51 mph.
Explanation:
The following data were obtained from the question:
Distance (d) = 147 miles
Time (t) = 2.47 hours.
Speed (S) =?
Speed is defined as the distance travelled per unit time. Mathematically, it is expressed as:
Speed (S) = Distance (d) / time (t)
S = d/t
With the above formula, we can obtain the speed of the girl as illustrated below:
Distance (d) = 147 miles
Time (t) = 2.47 hours.
Speed (S) =?
S = d/t
S = 147 miles / 2.47 hours.
S = 59.51 miles per hour (mph)
Thus, the speed of the girl is 59.51 mph.
A pitcher throws a 145 g baseball at a velocity of 30.00 m/s. How much kinetic energy does the ball have?
Final Answer:
65.25 J is the kinetic energy that the ball has.
Explanation:
M = 145g
(Reminder: kg must be used in this formula, thus we need to convert 145g to kg)
M = 145g x 1kg/1000g
(cross out g, then multiply 145 to 1kg)
M = 145kg/1000 = 0.145kg
M = 0.145 kg
V = 30.00 m/s
Solution:
KE = 1/2mv^2
KE = 1/2(0.145kg)(30.00m/s)^2
(Square first the velocity)
KE = 1/2(0.145kg)(900.00m^2/s^2)
KE = 1/2(130.5 kg*m^2/s^2)
KE = 65.25 kg*m^2/s^2
(Reminder: 1 kg*m^2/s^2 = 1 J)
KE = 65.25 J
Final Answer:
65.25 J is the kinetic energy that the ball has.

Answer: 5.4 kg
Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have
F = ma
where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).
Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.
m = F/a
m = (120)/(22.35) ≈ 5.4 kg
Hence, the eagle has a mass of approximately 5.4 kg."

Memories
by matthew smith
I remember when I met you
the smile on your face,
Seems like a million years ago -
a different time and place
I remember when I kissed you
the warmth inside my heart,
I thought it'd last a lifetime
I swore we'd never part
I thought about the future
I started making plans,
Forever you'd be my woman
forever I'd be your man
We went together places
so that everyone could see,
The women that I want to share
the rest of my life with me
I told you that I loved you
I told you that I cared,
I told you if you were falling
just look back and I'd be there
I know I didn't have all the answers
sometimes I only guessed,
But, through it all I have to say
"I always tried my best"
I wasn't always perfect
I wasn't always right,
I know sometimes I wasn't
even worthy in your sight
I know I took for granted
the love you had to share,
All I ever wanted was
for you to know I cared
Our lives have changed directions
as sometimes lovers do,
Often time and change
and pave a path that's new
Sometimes I often wondered
just what lies ahead,
Sometimes I'd like to turn back time
and take back what I said
We've both gone different places
we've both gone different ways,
I know sometimes I let you down
when trouble came our way
I know sometimes I did things
you didn't comprehend,
But, through the years and all the tears
our memories will never end........

Irene drops a clay ball at time t=0. The ball stops when it hits the ground. Which of the following graphs best shows the velocity v of the clay ball from when it is dropped until it hits the ground?
Answer:
Graph-
Explanation:
The graph best shows the velocity v of the clay ball from when it is dropped until it hits the ground is attached below.
What is velocity?Velocity is the time rate of change of displacement. The displacement and velocity both are vector quantities. They represent magnitude and direction as well.
Irene drops a clay ball at time t=0. The ball stops when it hits the ground.
When the clay ball drops, only force acting is due to acceleration due to gravity.
The velocity of the clay ball decreases with the time.
Thus, the graph best shows the velocity v of the clay ball from when it is dropped until it hits the ground is attached.

A 120-kg roller coaster cart is being tested on a new track, and a crash-test dummy
is loaded into it. The roller coaster starts from rest at point A which is 25 m above
point B. If the track near to point B is in the shape of a circle with a radius of 15 m,
and the cart is moving at 22 m/s at point B, what centripetal acceleration does the
cart experience at that point?
Answer:
32 m/s².
Explanation:
From the question given above, the following data were obtained:
Mass (m) of cart = 120 Kg
Radius (r) = 15 m
Velocity (v) = 22 m/s
Centripetal acceleration (a) =?
The centripetal acceleration experienced by the cart can be obtained as illustrated below:
a = v²/r
a = 22² / 15
a = 484 / 15
a = 32.27 ≈ 32 m/s²
Thus, the centripetal acceleration experienced by the cart is approximately 32 m/s².

Save and Exit

Answer:
The correct option is;
75 N
Explanation:
The given parameters are;
The angle of inclination of the ramp, θ = 42°
The gravitational force of the box = m × g = 112.1 N
Let [tex]F_f[/tex] represent the force of static friction acting on the box
Given that the box is at rest, we have
The component of the gravitational force acting along the inclined plane = The force of static friction acting on the box, [tex]F_f[/tex]
We have that the component of the gravitational force acting along the inclined plane = m × g × sin (θ) = [tex]F_f[/tex]
[tex]F_f[/tex] = m × g × sin (θ)
Substituting the values, gives;
[tex]F_f[/tex] = 112.1 × sin (42°) ≈ 75.0095409728
∴ The force of static friction acting on the box = [tex]F_f[/tex] ≈ 75 N
