Question

A body is moving with uniform velocity of 8m/s.when the body just crossed another body ,the second one starts and moves with uniform acceleration of 4m/s2 the time after which two bodies meet , will be

Answer 1

they will not meet at all

Answer 2

Answer:

Two bodies will be meet after 2 sec.

Explanation:

Given that,

Velocity of first body  = 8 m/s

Acceleration of second body$a = 4 m/s^2$

When the second body will be move with the velocity of the first body then both bodies will be meet.

We need find the time when two bodies will be meet

Using equation of motion

$v = u+at$

$8 =0+4t$

$t = 2\ sec$

Hence, Two bodies will be meet after 2 sec.
