Knowing the force and distance allows you to calculate the work done.
Then, if you know the TIME, you can calculate the power.
“In the scientific method, observations lead to questions that require answers. In the scientific method, the hypothesis is a testable statement proposed to answer a question.” I hope this helps you for what your looking for
Answer: D
Reduced impact time will increase the impact force
Explanation: Collision occurs when two or more bodies collide and exert forces on each other within a short time.
If a body of mass M moving with a velocity V collide with another body, the kinetic energy of the body is equal to the work done by the body.
That is, K.E = 1/2mv^2 = F × s
Where workdone = Force × distance
Make F the subject of formula
Mv^2/2s = F
But V = distance s/time t
Substitute for V
Ms^2/2t^2s = F
Ms/2t^2 = F
From the equation above, we can deduce that F is inversely proportional to the square of time.
Therefore, the reduced impact time will increase the impact force
The gravitational force between Susie and Troy is d) 
Explanation:
The magnitude of the gravitational force between two objects is given by
where
:
is the gravitational constant
m1, m2 are the masses of the two objects
r is the distance between them
In this problem:
is Susie mass
is Troy mass
r = 2 m is the distance between them
Substituting into the equation, we find the gravitational force between Susie and Troy:

Answer:
Since velocity is a speed and a direction, there are only two ways for you to accelerate
Explanation:
change your speed or change your direction—or change both.
