Question

The truck of a passenger car applies brakes at a velocity of 30 m/s and comes to rest 5 seconds later. What is the deceleration?

Answer 1

(30 m/s)/(5s) = 30/5 = 6 m/s^2

Answer 2

It's very important tho it helps me whenever I've physics assignments

Answer 3

Let have the final velocity=30 u=0
D=v-u/t
=30-0/5
=6s
