Center of mass of automobile truck system from traffic light

Reference no: EM13662577

A 1700 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 of3.0 m/s 2. At the same instant a2200 kg truck, travelling at a constant speed of 6.0 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 = 3.0s?

b) What is the speed of the center of mass of the automobile-truck system then?
