Question

A car is travelling at 20 km/h, it speeds up to 60 km /h in 6 seconds . What is its acceleration

Answer 1

Explanation:

initial velocity , u= 20km/h = 5.55m/s

final velocity , v= 60km/h = 16.66m/s

time , t = 6 secs

a= final velocity - initial velocity / time = v-u/t

= 16.66-5.55/6 = 11.11/6 = 1.85 m/s^2
