Question

a ball thrown vertically upward Rises Rises up to a height of 20m then it returns back to the initial position calculate first the total distance covered by the ball second the displacement of the ball

Answer 1

Answer:

(1):40m

(2):0m

Explanation:

rhe path travelled by a projectile is symmetric

Answer 2

Answer:

total distance=40m

total displacement=0m

Explanation:

1. as the ball is thrown upward the distance covered by the ball while going up is 20m and while coming down the distance is again 20m.So the total distance is sun of both i.e.40m.
2. the total displacement is zero as the initial position coincides with the final position..

hope it hepls..
