Question

A bus accelerates uniformly from 54km/h to 72km/h in 10 seconds. Calculate acceleration and distance travelled
​

Answer 1

Answer:

u=54km/h which is = 15m/s

v=72km/h which is=20m/s

a=v-u/t=20-15/10=1/2m/s square..

distance travelled is=2as=:v square-u square

2x1/2s=400-225

s=165m..
