Question

A body initially at rest covers a distance of 0.8km in 5s with constant acceleration . Calculate the acceleration​

Answer 1

Explanation:

0.8=1/2at²

h=1/2at²......by using this formula

1.6=at²

1.6=a(5)²

1.6=ax25

1.6/25=a

solve this u get urs answer perfectly

Answer 2

Answer:

Explanation:

0.8 KM =800 m

t=5s

let the acceleration be a

using equation s=ut+1/2 at^2

800=0 t + 1/2 a 25

a= 64 m/s^2
