A projectile of mass 4kg is fired vertically and reaches a maximum height of 40m. Calculate the potential energy at the highest point
(g = 10ms(^{-2})

  • A.
    1800J
  • B.
    1600J
  • C.
    600J
  • D.
    440J
Explanation

Potential energy at the highest point = mgh
PE = 4 × 10 × 40 = 1600J

There is an explanation video available below.
