Question

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

Answer 1

Answer:

Given u=0, t=5s , s=100m

a=?

s=ut+1/2at²(newton 's eqn of motions.)

s=1/2at²( as u=0 )

s=

1/2×a×5²

1/2×a×25

25a/2=100 ( as s=100)

25a=100×2

a=100×2÷25

a=8ms-²
