A heavy truck and a small car roll down a hill at the same speed and need to stop in the same amount of time. Compared with the force to stop the car, the force needed to stop the truck is? A) greater. B) smaller C) the same.Explanation / Answer
(30)
The ball exerts a force on bat of 1000 N (action - reaction force).
(31)
The force of impact is same for both.
(32).
Momentum = m*v
when you ride twice as fast as you have,
almost twice the momentum.
(33)
As given that mass is twice,
so momentum is doubled.
