Question

A car accelerate uniformly from 36 km/h to 72 km /h in 10 seconds. Calculate a.theacceleraionb. the distance covered by the car in that time

Answer 1

On converting 36km/h in m/s we get u= 10m/s And v=72km/h=20 m/s Now a=v-u/t =20-10/10 =1 m/s Distance covered= s=ut+½at² =10×10+½×1(10)² =150 m
