What best describes the greatest height a ball will bounce off the ground after being dropped from a height of 60 centimeters? a. less than 60 centimeters, as the ball transforms a part of its potential energy into heat energy b. less than 60 centimeters, as the ball transforms some of its heat energy into potential energy c. more than 60 centimeters, as the ball transforms some of its heat energy into potential energy d. more than 60 centimeters, as the ball transforms some of its potential energy into heat energy

A. Less than 60 centimeters, as the ball transforms a part of its potential energy into heat energy

Explanation:

As we know that the ball is dropped from the height of 60 cm

so here initial total energy of the ball is in the form of gravitational potential energy

now when ball is dropped and bounced back to some other height then during the motion of ball it must have encounter some air drag or friction force.

Due to this air drag or friction force the ball must lose some of its potential energy due to which the final height achieved by the ball after it bounce back will be less than the initial height.

so correct answer will be

A. Less than 60 centimeters, as the ball transforms a part of its potential energy into heat energy
