A boy throw a ball ertically upwards and catches it after 2 seconds. Which of the following is true regrading the motion of the ball?
(a) The displacement is zero
(b) Magnitude of acceleration is constant

Options

A. Only (a) is true
B. Only (b) is true
C. Both (a) and (b) are true
D. Both (a) and (b) are false

Explanation

The initial and final positions of the body are same. Therefore is zero and acceleration of the body is equal to the acceleraton due to gravity and it is a constant
