Kinetic Energy Problems 1. A table tennis ball has a mass of about 2.45 g. Suppose the ball is hit across the table with a speed of 4.0 m/s. What is the ball’s kinetic energy?

2. The largest land predator is a male polar bear, which has a mass of around 500.00 kg. If the top speed of a male polar bear is 11.0 m/s, how much KE does it have?

3. What is the KE of a 1.00 kg hammer swinging at 20.0 m/s?

4. Japan’s fasted high speed “bullet” trains, also known as the Shinkansen, travel at a speed of 88.9 m/s. It has an estimated mass of 480,000.0 kg. What is the maximum KE of this train?
