Question

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

Answer 1

Explanation:

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

Answer:

1.11 m/s²

Explanation:

Acceleration = ∆ velocity / ∆time

Time is constant.

V1 = 80 km/h

V2 = 60 km/h

V1 - V2 = 80 - 60 = 20 km/h = 5.55 m/s

Acceleration = 5.55 / 5 = -1.11 m/s²( there is negative acceleration as the speed is decreasing)
