I have no idea how to solve these problems. please help me understand all or any!
1. Your car is broken, so you are pushing it. If your car has a mass of 800 kg, how much momentum does it have when it's moving forward at
3 m/s (11km/h)???
2. you begin pushing the car forward from rest. Neglecting friction, how long will it take you to push your car up to a speed of 3 m/s on a level surface if you exert a constant force of 200 N on it?
3. When your car is moving at 3m/s, how much translational kinetic energy does it have?
4. No one is driving your car and it crashes into a parked car at 3m/s. Your car comes to a stop in just 0.1s. what force did the parked car exert on it to stop it that quickly?
