Answer 1

Answer: A 60 g golf ball is dropped from a level of 2 m high. It rebounds to 1.5 m. Energy loss will be 0.29J

Explanation: To find the correct answer, we have to know more about the Gravitational potential energy.

What is gravitational potential energy?

• The energy possessed by a body by virtue of its position in gravitational field of earth is called gravitational potential energy.
• The gravitational potential energy of a body at a height h with respect to the height h will be,

                                          $U=mgh$

• Expression for gravitational potential energy loss will be,

                                        $E=U_i-U_f$

How to solve the problem?

• The total energy before the ball dropped will be,

                 $U_i=mgh_i=60*10^-3kg*9.8m/s^2*2m=1.176 J$

• The total energy after when the ball rebounds to 1.5m will be,

                 $U_f=mgh_f=60*10^-3kg*9.8m/s^2*1.5m=0.882J$

• The total energy loss will be,

                $E=1.176-0.882=0.294J$

Thus, we can conclude that, the energy loss will be,0.294J.
