A 60 kg pupil runs for 600m in 1 minute uniformly (a)calculate his velocity (b)calculate his kinetic energy
(c)if eating one banana enables a pupil to perform about 3kg of work how many bananas should he eat?​

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
