Question

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

Answer 1

Answer:

1.1m/s

Explanation:

acceleration = change in velocity / time

 (1)  change km/hr to m/s

                 change in velocity = 80-60

                                               =  20 km/hr

                                               = 20 x 5/18

                                              =5.5 m/s

acceleration  = 5.5/5 =1.1 m/s
