Question

A body moves in uniform acceleration of 0.5m/sec. If the initial velocity is 20m/sec. Find its velocity after 6sec

Answer 1

Explanation:

Given,

acceleration (a) - 0.5 m/s²

initial velocity(u) - 20m/ s

time taken (t) - 6 sec

using first eqn of motion:

v= u+at

v= 20 + 0.5× 6

v= 20+ 3.0

v= 23 m/s.
