Question

4. A driver applies the brakes and slows down the velocity of the bus from 80 km/hr to 60 km/hr in 5 seconds. What will be the acceleration of the bus?

Answer 1

Answer:

-1. 112

Explanation:

1 km/h = 0.278m/s

so 80 km/h= 22.24

60km/h= 16.68

v=16.68

u=22.24

t=5

A= v-u/t

A=-1.112
