Question

11. A car has a starting velocity of 12 m/s and a final velocity of 2 m/s in 4 seconds. What is the

acceleration of the car?

Answer 1

the acceleration is the change in velocity according to time

we have starting velocity with 12 m/s

and the final velocity is 2 m/s

so ,the velocity differences is 12-2=10 m/s

the acceleration will be 10÷4=2.5 m/s^2
