Question

A leap of 1m takes 1s.After every 5 leaps taken in forward direction,3 leaps in the backward direction are taken .In a journey of 13m A) Average velocity=2.5m/s B) Total time=23s C) Total Displacement required is 6m D) Total time =37s

Answer 1

Answer:

Explanation:

Time taken to move first 5 m forward = 5

S.

Time taken to move 3 m backward = 3 s.

Net distance covered = 5-3=2 m.

Net time taken to cover 2 m = 8 s.

Drunkard covers 2 m in 8 s.

Drunkard covered 4 m in 16 s.

Drunkard covered 6 m in 24 s.

Drunkard covered 8 m in 32 s.

In the next 5 s, the drunkard will cover a distance of 5 m and a total distance of 13 m and falls into the pit.

Net time taken by the drunkard to cover 13 m= 32+5 37 s.
