A bus travelling at 60 m⁄s takes 10s to come to halt, its deceleration is equal to?

Assuming the bus undergoes constant acceleration, it is given by:

a = (Vf-Vi) / Δt

a is the acceleration, Vf is the final velocity, Vi is the initial velocity, and Δt is the elapsed time.

Given values:

Vf = 0m/s (slows to rest)

Vi = 60m/s

Δt = 10s

Plug in the values and solve for a:

a = (0-60) / 10

a = - 6m/s²

The bus decelerates at a rate of 6m/s².
