What is the acceleration of a bike that's goes from 38km/hr to a stop in 4.5 s?

The acceleration of a bike is 2.34 m/s².

Explanation:

Given that,

Velocity = 38 km/hr

Time = 4.5 s

We need to calculate the acceleration

Using equation of motion

Where, v = final velocity

u = initial velocity

t = time

Put the value in to the formula

Negative sign shows the deceleration.

Hence, The acceleration of a bike is 2.34 m/s².
