Question

A car moving south speeds up from 10 m/s to 40 m/s in 15 seconds. What is the car’s acceleration?

Answer 1

Step-by-step explanation:

Initial velocity ( u ) = 10 m/s

Final velocity ( v ) = 40 m/s

Time taken ( t ) = 15 second

Now

`acceleration = (v - u)/(t) \\ = (40 - 10)/(15) \\ = 2m /{s}^(2)`
