Question

A body moves with v=10 m/s , s=50 m and the relation between s and t is as follows s=t^2 + 5t . Find the u and a.

Answer 1

uniform velocity means no acceleration so v =u +at becomes v= u

velocity after 5 seconds is also same as velocity at 0 seconds =10 m/ s

distance covered in 5 seconds s.= ut+ 0.5 at 2

a =0

so.......

10× 5 =50m
