Read each question carefully and show all your work. Use appropriate units for your answers. Round your final answers to two decimal places where necessary.
1. A car with a mass of 1200 kg accelerates uniformly from rest to a speed of 20 m/s in 8 seconds. Calculate the net force acting on the car.
2. If a force of 50 N is applied to move an object 10 meters in the direction of the force, the work done is Joules.
3. An object with a mass of 5 kg is raised to a height of 3 meters. Its gravitational potential energy is Joules (assume g = 9.8 m/s²).
4. A ball is dropped from a height of 45 meters. Approximately how long does it take to hit the ground? (Neglect air resistance, g = 9.8 m/s²)
1.5 seconds
3.0 seconds
4.5 seconds
9.0 seconds
5. A motor lifts a 200 kg load to a height of 5 meters in 10 seconds. Calculate the power output of the motor. (g = 9.8 m/s²)
6. The unit of force in the SI system is the Joule.
