Question

A car moving with uniform acceleration travels 75 m in the first 8 s and 180 m in the next 10 s. Find (i) the initial velocity, and (ii) the acceleration of the body.

Answer 1

Answer:

Explanation:

s=ut+(0.5)a$t^{2}$

75=8u+32a   .....(1)

180=10u+50a   ...(2)

solving equ we get,

u=34.4m/s

a=8.6m/$s^{2}$
