Question

A body is moving with a velocity of 10 m/s at A and is moving with a velocity of 20 m/s when it reaches B. If the distance between A and B is 15m. Find the acceleration of the body​

Answer 1

Answer:

Suppose the acceleration is a then using the second equation of motion, s=ut+

and putting t=2sec and u=10m/s

we get 20=10×2+a×2

or a=0 that is uniform motion.
