Question

the velocity of a body moving along straight line with uniform acceleration a reduces by 3/4 of its initial velocity in time t .the total time of motion of the body till it's velocity becomes zero is​

Answer 1

Answer:

1

Explanation:

Answer 2

v = u + at

 

u/4 = u - at

 

a = 3u/4t   (i)

 

again use equation v = u +at

 

0 = u -at'

 

t' = u/a

 

substitute a from eqn. (i)

 

t' = u/(3u/4t)

 

t' = 4t/3
