Question

A particle is projected from a point on ground with initial speed of 10 m/sec at an angle of 37º with the horizontal. At the same instant a fly starts flying on the same path of particle with constant speed of 10 m/s Then :

(A) time taken by fly to complete whole path is less then time taken by particle

(B) acceleration of fly is zero

(C) average velocity of both are same for whole journey

(D) None of these

Answer 1

Correct option (A*) time taken by fly to complete whole path is less then time taken by particle

Explanation:

t =  distance/speed

Since, speed of fly ≥ speed of particle so time taken by fly is less.
