Read each question carefully and show all your work. Use appropriate units for all answers.
1. A car accelerates uniformly from rest to a speed of 25 m/s in 10 seconds. Calculate the acceleration of the car.
2. A ball is thrown vertically upwards with an initial velocity of 20 m/s. How high does it go?
3. A net force of 100 N acts on a 20 kg object. What is the acceleration of the object?
2 m/s²
5 m/s²
10 m/s²
20 m/s²
4. The work done on an object is equal to the change in its energy.
5. Power is defined as the rate at which is done.
6. For the circuit shown below, if R1 = 10 Ω, R2 = 20 Ω, and the voltage source is 12 V, calculate the total current flowing through the circuit.
7. The speed of light in a vacuum is approximately 3 x 10^8 m/s.
