Answer:
The acceleration of the bus that decreases its speed from 80 kilometers per hour to 60 km per hour in 5 seconds is -1.12m/s2
Explanation:
Acceleration a = (V - U) / t
Given: 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
