Question

Calculate the acceleration of a bus whose speed changes from 7 m/s to 16 m/s over a period of 5s

Answer 1

To calculate the average acceleration, the first step is to calculate the speed and time variation.

Data:

A = (acceleration) = ?
ΔV = (Vf - Vi)
Vi (Initial velocity) = 7 m/s
Vf (Final velocity) = 16 m/s
Δt (period) = 5s

Solving:

`A = (\Delta\:V)/(\Delta\;T)`

`A = (Vf - Vi)/(\Delta\:T)`

`A = (16 - 7)/(5)`

`A = (9)/(5)`

`\boxed{\boxed{A = 1.8\:m/s^2}}\end{array}}\qquad\quad\checkmark`
