Find the acceleration of the bus.​

Answer 1

Answer:

Motion. A bus decreases its speed from 80 km/h to 60 km/h in 5 seconds. Find the acceleration of the bus. So, the bus is decelerating at a rate of -1.11 m/s2.

Answer 2

Explanation:

80km/h = 80*1000/3600 m/s = 22.2 m/s

similarly 60km/h = 60*1000/3600 m/s = 16.6 m/s

acceleration is change in velocity over time

which is (22.2-16.6)/5= 1.12 m/s^2
