Question

If a ball is thrown up with a certain velocity. Ball attains a height of 40 m and comes back to the thrower, then

• A. total distance covered by ball is $40m$.
• B. total displacement covered by ball is $80m$.
• C. total displacement is zero.
• D. total distance covered by ball is zero.

Answer 1

The correct option is C total displacement is zero.

Total distance covered is 40m + 40m = 80 m
Displacement is the shortest path available to the destination. Since the final destination of the ball is same as the initial point , total displacement is zero
