A truck accelerates From being stopped to 18 m/s in 5.5 seconds. A bus accelerates from being stopped to 24 m/s in 6.0 seconds. Which vehicle has a higher acceleration

The bus

Explanation:

a = (v-u) / t

Where

a = acceleration

v = final velocity

u = initial velocity

t = time taken

For truck to get its acceleration,

a = (18-0) / 5.5 = 3.27 ms⁻²

For bus to get its acceleration,

a = (24-0) / 6 = 4 ms⁻²

As 4 > 3.27 bus has a greater acceleration.
