Question

A car starting from rest travels 100 m in
5s with uniform acceleration. Find the accel-
eration of the car.​

Answer 1

Answer:

a = 8

Explanation:

s = ut + 1/2 a t^2

u = 0 (since starts from rest)

s = 1/2 a t^2

100 = 1/2 a (5)^2

a = 8

Answer 2

s=100m

u=0m/s

t=5s

using s=ut+1/2at^2

100m=0*5+1/2a5^2

100=0+1/2a25

100=25a/2

200=25a

a=200/25

a=8m/s^2 ans
