1. A car slams on brakes and comes to a stop after having been traveling 40m/s. The car stops in
only 0.5s. What is the car's acceleration? (Units for acceleration should be typed as m/s/s right
next to the number!)

Respuesta :

Answer:

-80 m/s/s

Explanation:

acceleration = (v final - v initial) / time

a = (0 m/s - 40m/s) / 0.5 seconds

a = - 40 m/s / 0.5 seconds

a = - 80 m/s/s
