IMAT 2016 Q59 [Projected Ball]

A ball is projected vertically upwards and then falls back to its original position.

Once projected, the ball experiences only a single force, downwards, due to a constant gravitational field strength of 10 N/kg.

Here are three statements about the ball:

  1. When the ball is moving upwards it loses kinetic energy and gains potential energy.
  2. The magnitude of the ball’s acceleration increases as it falls.
  3. No vertical forces act on the ball when it is at its maximum height

Which of the statement(s) is/are correct?

A. 2 and 3 only
B. none of them
C. 1 and 2 only
D. 3 only
E. 1 only
