Answer:
a
b
c
Explanation:
Considering the first question
From the question we are told that
The force produced is 
The duration of the punch is 
Generally the impulse delivered is mathematically represented as
=> 
=>
Considering the second question
The approaching velocity of the ball is 
The leaving velocity of the ball is 
The mass of the ball is 
Generally the magnitude of the impulse delivered is mathematically represented as
=> ![I_1 = [0.145 * 45] - [0.145 * -53]](https://tex.z-dn.net/?f=I_1%20%3D%20%20%5B0.145%20%2A%20%2045%5D%20%20-%20%5B0.145%20%2A%20-53%5D)
=>
Considering the third question
The duration of the impact of the bat is 
Generally the average force exerted by the bat is mathematically represented as
=> 
=>
Probably not. The elevator has security system just like any device. It will automatically trigger breaks in case it detects some sort of free fall.
Person inside free falling elevator could experience 0G or no gravity effect something similar to what astronauts experience in earth's orbit.
The only damage that could happen to you is when the breaks are released you won't feel 0G anymore and fall about 4ft to the floor of the elevator.
Hope this helps.
