Question

A body starts from rest and travels with uniform acceleration on a straight line if its velocity after making a displacement of 32 m is 8ms it's acceleration is

Answer 1

Initial velocity of body

u=0

Let the acceleration be a.

Using

v=u+at

We get

v=0+an

⟹ a= v/n

For displacement in last two seconds,

t=2

Using

S=vt− at ^2/2

Or S=v(2)− v/2n (2) ^2

= 2v(n−1)/n
