asked 08/28/22Constant velocity and acceleration
A sports car moving at constant velocity travels 120 m in 5.0 s. If it then brakes and comes to a stop in 4.0 s, what is the magnitude of its acceleration (assumed constant) in m/s2, and in g’s (g = 9.80 m/s2)?

v = s/t = 120m/5s = 24 m/s; 0 = 24 + 4a; a = -24/4 = - 6 m/s2 = - 6/9.8·g = - 0.61g
