Question

A bus decreases its speed from 72 kmph to 54 kmph in 5s. Find the
acceleration of the bus.​

Answer 1

Explanation:

a=v-u/t

a=54-72/5

a=-18/5

a=-3.6m/s^2

Answer 2

Answer:

the acceleration is 1 m per second square. first first take difference of 72 kilometre per hour and 18 kilometre per hour and convert into seconds then you will get 5. metre per second. acceleration is difference in velocity to the time taken so 5 by 5 is 1 metre per second square
