A motorcycle that is stopped at a traffic light accelerates at 4.20 m/s2 at the moment the green light turns on. At that moment, a car traveling at 72.0 km/h passes the motorcyclist. It accelerates for a time T, and then retains its speed. It overtakes the car 42.0 s after starting off. How fast is the motorcyclist going when he passes and how far is he from the traffic light at that moment? Construct the graphs of X vs t, V vs t, and A vs t.
