Question

A car starting from rest and moving with uniform acceleration attains a speed of 72 km per hour

in 5s. Find its acceleration.​

Answer 1

Answer:

Acceleration= 4m/s^2

Explanation:

Given, initial velocity= 0m/s

final velocity= 72km/h= 20m/s

time= 5s

So, from- v=u+at, we get:-

20= 0 + a × 5 => (20-0)/5= 4m/s^2
