Question

A car acceleration from rest to 30m/s in 10seconds. What is it's acceleration?

Answer 1

`3m/s^2`

Step-by-step explanation:

Apply the uniforma acceleration equation
`v=u+at`

v = Final velocity of the car

u = Initial velocity of the car

a = Acceleration of the car

t = Time taken for the car to reach its final velocity

Since the car starts from rest, initial velocity
`u=0m/s`

`30 = 0 + a(10)`

`a = 3m/s^2`
