Question

A stone is thrown upwards as shown in the diagram. When it reaches $P,$ which of the following has the greatest value for the stone?

• A. its acceleration
• B. its kinetic energy
• C. its potential energy
• D. its weight

Answer 1

Answer: (C)

its potential energy

P is the highest point of the ball during its motion. At this point, its speed will be zero. This makes the kinetic energy to be zero. The acceleration remains constant all through the motion and the weight depends on the value of acceleration due to gravity. So weight will also be constant.

So, the correct answer is c) its potential energy.
