Question

An object A moves with a uniform acceleration and zero initial velocity. Another object , starts from the same point, moves in the same direction with a constant velocity . The two objects meet after a time t. The value of t is _______.

Answer 1

Answer: 2u/a

Explanation:

Object A.....

By second equation of motion,

Distance = 0*t + 1/2 *a *t^2

= 1/2 *a *t^2........

Object B.......

Distance = ut.......

For them to meet, distance travelled must be equal....

Thus, ut = 1/2 a t^2

So, t = 2u/a

Answer 2

Answer:

value of t is 2u/a

Explanation:

hope it helps u...
