Question

A bus decreases its speed from 80 kmph to 60 kmph in 5s.Find the acceleration of the bus​

Answer 1

Explanation:

initial velocity (u) = 80kmph

Final velocity (v) = 60kmph

Time = 5 seconds

Acceleration = v-u/t

=80-60/5

= 20/5

=4m/s ^2

so acceleration is -4 m/s ^2 because the speed is decreasing.
