A 950 kg automobile is at rest at a traffic signal. At the instant the light turns green, the automobile starts to move with a constant acceleration of 2.6 m/s2. At the same instant a 1950 kg truck, traveling at a constant speed of 6.8 m/s, overtakes and passes the automobile.
a. How far is the center of mass of the automobile-truck system from the traffic light at t = 3.0 s?
b. What is the speed of the com then?
