# Question: You are driving slowly in the right lane of a

You are driving slowly in the right lane of a straight country road. For a while, a car to your left has lagged 50.0 m behind you at the same speed of 25.0 mi/h. Suddenly that car speeds up and passes you, traveling at a constant acceleration until it is 40.0 m in front of you 7.00 s later.

(a) Qualitatively sketch the location-versus-time graphs for both cars on the same axes, letting t = 0 be the start of the acceleration, and x = 0 be the location of the other car at that time.

(b) Determine the other car’s acceleration.

(c) How far did each of you travel during the passing procedure?

(d) What is the other car’s speed at the end of the passing procedure?
