Question

A ball is thrown upwards from a point A. it reaches up to the highest point B and returns.
Potential energy at A = kinetic energy at B
Potential energy at A = potential energy at B
Potential energy at A = kinetic energy at A
Kinetic energy at A = kinetic energy at B

I selected the last option am I correct and if not why not ??

Answer 1

Answer:

A ball is thrown upwards from a point A. it reaches up to the highest point B and returns.

Potential energy at A = kinetic energy at B

Potential energy at A = potential energy at B

Potential energy at A = kinetic energy at A

Kinetic energy at A = kinetic energy at B
