Question

Which among the following has the highest kinetic energy. Each one is moving with the speed of 10 m/s?

• A. A person running down a hill.
• B. A ball running down a hill.
• C. A car driving down a hill.
• D. A box sliding down a hill.

Answer 1

The correct option is C A car driving down a hill.

Kinetic energy of an object depends on the mass and the velocity of an object. As all are moving with the same velocity therefore , the object possessing more mass has more kinetic energy. Hence, the car driving down a hill possess more kinetic energy.
