A ball is projected upwards. Its acceleration at the highest point is

Options

  1. AZero
  2. Bdirected upwards
  3. Cdirected downwards
  4. Dsuch as cannot be predicted

Correct answer

C. directed downwards

Step-by-step solution

A force is only required to maintain an acceleration. And in the case of a projectile that is moving upward, there is a downward force and a downward acceleration. That is, the object is moving upward and slowing down.
