Question

a bus decreases its speed from 108 km/h to 198 km/h in 5s. find the acceleration of the bus​

Answer 1

Acceleration is the rate of change of velocity with respect to time.

v1 = 108 km/h or 30 m/s

v2 = 198 or 55 m/s

Time = 5 sec

Acceleration = ( v2 - v1 ) / t

Acceleration = ( 55 - 30 ) / 5

Acceleration = 5 m/s^2
