You are driving at the speed of 31.9 m/s (71 . 3735 mph) when suddenly the car in front of you (previously traveling at the samespeed) brakes. Considering an average humanreaction, you press the brakes 0.527 s later.Assume that the brakes on both cars are fullyengaged and that the coefficient of friction is0.773 between both cars and the road.The acceleration of gravity is 9.8 m/s2.Calculate the magnitude of the accelerationof the car in front of you when it brakes.
