1. A 1500 kg car travelling at 80.0 km/h comes to a screeching halt in a timeof 4.00 seconds. Calculate the force of friction experienced by the car.

2. A 1.00 kg ball travelling towards q soccer player at a velocity of 5.00 m/s rebounds off the soccer player's foot at a velocity of 8.50 m/s. If the time of contact between the ball and the player's foot was 0.02 seconds, what was the force that the foot applied on the ball?
