Question

bus accelerates uniformly from 54 kilometre per hour to 72 kilometre per hour in 10 seconds calculate acceleration in S1 system​

Answer 1

Answer:

The answer is 0.5ms/2

Explanation:

We know,

u = 54kmph = 15mps

v = 72kmph = 20mps

t = 10s

Therefore,

acceleration = v-u/t

                       = 20-15/10 = 1/2 = 0.5ms/2

Hope this helps you
