Question

A ball is thrown vertically upwards. It rises upto a height of 10 m, and comes back to the initial position. Calculate(i) total distance covered by the ball (ii) the displacement of the ball

Answer 1

1) distance = 2h
= 2 × 10
= 20
2) displacement = 0

Answer 2

Answer:

The ball rises up to a height of 10 metre and again came down with the same height of 10 metre.

i) The total distance covered by the object is=(distance it rises up+distance it came down).

=>(10+10)m=20m.

ii)The ball starts from point A from ground and reaches the same point A on ground. So, there is no change in the position of the ball. Therefore, the displacement is zero.
