Question

Q9) A ball is thrown vertically upwards it
reaches a maximum height H. It then returns
to the ground. Calculate the distance travelled
and the displacement.​

Answer 1

Answer:

Distance = 2H

Displacement = 0 ( as initial point and final point are the same)

Answer 2

Answer:

Distance travelled = 2H

Displacement = 0

Explanation:

Highest point reached by the ball = H

The ball went vertically upwards and then returned back to ground;

Therefore, Distance travelled = H + H

= 2H

Since, the initial and final point coincide with each other thus, displacement = 0
