Question

A bus decreases its speed from 80 km / hour to 60 km / hr in 5 socond .find the acceleration of the bus​

Answer 1

Answer:

-1.12m/s2

Step-by-step explanation:

Initial velocity (U) = 80 km/hr = 80 × 5/18 = 400/18 = 22.2m/sec

Final velocity (V) = 60 km/hr = 60 × 5/18 = 300/18 = 16.6m/sec

Acceleration a = (V - U) / t

= (16.6 - 22.2)/5

= -5.6/5

= -1.12 m/s2
