1. A 14 700 N car is traveling at 5m/s. The brakes are suddenly applied and the car slides to a stop. The average braking force between the tires and the road is 7000N. How far will the car slide once the brakes are applied?
2. An 80N force pushes a 20kg mass 15m across a floor. Calculate the amount of work that is done.
3. A force of 300N is used to push a 145kg mass 30m in 3s.
a) Calculate the work done on the mass.
b) Calculate the power
