1- A soccer player accelerates a 1.20-kg ball from rest to 8.0 m/s during the 0.2 s in which her foot is in contact with the ball. What average force does she apply to the ball during the kick?

2- A thrown stone hits a window, but doesn’t break it. Instead it reverses direction and ends up on the ground below the window. In this case, we know:

b. the force of the stone on the glass = the force of the glass on the stone.
c. the force of the stone on the glass < the force of the glass on the stone.
d. the stone didn’t slow down as it broke the glass.

3- A freight train has a mass of 1.7 × 107 kg. If the locomotive can exert a constant pull of 8.0× 105 N, how long does it take to increase the speed of the train from rest to 100 km/h?
