A ball is thrown upward with an initial velocity of 22.0 m/s. If
the gravitational acceleration is –9.81 meters per second
squared, what is the maximum height the ball will reach?
Select one:
2.24 m.
24.7 m.
4.48 m.
49.4 m.
Answers
The maximum height reached by the ball during the upward motion is 24.7 m.
The given parameters;
initial velocity of the ball, u = 22 m/sThe maximum height reached by the ball is determined using the third kinematic equation as shown below;
v² = u² - 2gh
where;
v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball0 = u² - 2gh
2gh = u²
[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]
Thus, the maximum height reached by the ball during the upward motion is 24.7 m.

Scenario: On October 15, 1997, a car called
Thrust SSC set a new land-speed record. It
traveled 763 mph in 1 mile and became the first
car to officially break the sound barrier. The
Thrust SSC propels itself forward with two jet
engines made by Rolls-Royce, the same
engines found in the British version of the F-4
Phantom I fighter jet. The propulsion system
on the Thrust SSC is unique in that it does not
rely on the friction between the tires and the
ground for its forward motion. Instead, the jet
engines provide the force.
Question : Is it possible to make the Thrust SSC achieve an even higher maximum speed?
Directions: Use the information above and your
knowledge of Newton's second law of motion
to write a scientific explanation with at least
two modifications that you could make to the
car that would increase its acceleration. Be
sure to state a claim, provide mathematical
evidence (i.e. an equation or scientific
principle), and state your reasoning.
Thrust SC Specifications
Mass
10,700 kg
Maximum Speed
763 mph
Acceleration

Fuel Burn Rate

Thrust Force

We want to see if the Trust SSC can archive a higher maximum speed.
Remember the second Newton's law:
Force = mass*acceleration.
And acceleration is the rate of change of the velocity.
Assuming the mass of the Trust SSC does not change, increasing the force would mean that we increase the acceleration, and thus, larger velocities can be reached.
Now there are some problems.
How we do increase the force?.
It is hard to ve precise, mostly because we don't really know how the system works, we just got some given random data that we can't use without context.
Another thing we need to remember, this velocity is measured in only one mile. So because we have a fixed distance to measure it, we only can get larger velocities by increasing the acceleration.
And to increase the acceleration we can increase the force, as discussed, or, decrease the mass.
How to decrease the mass? Using lighter materials.
Now let's see an example on how decreasing the mass would affect the acceleration.
Mass = 10,700kgAcceleration = 20.8 m/s^2Then an aproximate force is given by:
F = 10,700kg*20.8 m/s^2 = 222,560 N
Now, if we decrease the mass a little bit, for example to 10,000kg, and we do not change the force, the new acceleration will be given by:
10,000kg*a = 222,560 N
a = (222,560 N)/(10,000kg) = 22.3 m/s^2
So decreasing the mass a little, increases the acceleration, which would make a larger maximum velocity.
Concluding, there are two ways of increasing the maximum velocity:
Increasing the force.
Decreasing the mass of the car.

Answers
Explanation:
The SI base units for newtons is: kg x m/s ².
When separated it is basically: the amount of force that one kilogram multiplied by one meter per second squared (this is the acceleration)
One Newton can be defined as the amount of force that would give a mass of one kilogram an acceleration of one meter per second per second.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
A spring balance can be used to calculate the Force. Newton is the SI unit of force.
From Newton's second law of motion: we know that:
Force = mass × acceleration
Now in SI system:
Unit of force is Newton.
Unit of mass is kg and unit of acceleration is meter per square second.
Hence, one Newton force can be defined as:
The required force to generate 1 meter per square second acceleration on an object of mass one kilogram.

which of the following is an example of the law of multiple proportions?
Answers
The answer option which is an example of the law of multiple proportions is: B) Two different compounds formed from carbon and oxygen have the following mass ratios: 1.33 g O: 1 g C and 2.66 g O: 1 g C.
The Law of Multiple Proportions is also referred to as Dalton's Law and it states that when two chemical elements combine to form more than one chemical compound, the masses (weights) of one chemical element that combine with a fixed mass (weight) of the other chemical element will always be in a ratio of small whole numbers.
According to the Law of Multiple Proportions, when two chemical elements combine to form two different chemical compound, the masses (weights) of one chemical element that combine with 1 gram of the other chemical element can be expressed as a ratio of small whole numbers.
For example, carbon and oxygen react to form either carbon monoxide and carbon dioxide.
Carbon monoxide (CO):
12 grams of C = 16 grams of O.
1 gram of C = 1.33 gram of O.
Carbon dioxide ([tex]CO_2[/tex]):
12 gram of C = 32 grams of O.
1 gram of C = 2.66 gram of O.
Ratio of oxygen (O) = 16:32 = 1:2 (Law of Multiple Proportions).
