1. A 62.3kg swimmer jumps off a 10.0m tower.
   1. Find the swimmer's velocity when hitting the water.
   2. The swimmer comes to a stop 2.00m below the surface. Find the net force exerted by the water.
2. You are driving a 2500.0kg car at a constant speed of 25.0m/s along an icy, but straight and level road. While approaching a traffic light, it turns red. You slam on the brakes. Your wheels lock, the tires begin skidding and the car slides to a halt in a distance of 54.3m. What is the coefficient of sliding friction between your tires and the icy roadbed?

Could you help me with these forces questions?
