Pls help me.

Question 6 A 108 m long train starts from rest (at t = 0) and accelerates uniformly. At the same time, a car moving with constant velocity in the same direction is in line with the rear end of the train, as shown in Figure A1.06. At t = 12.0s the car reaches the front end of the train. However, the train continues to speed up and pulls ahead of the car. Att = 30.0s, the car is left behind the train. Calculate a. the car's speed. b. the train's acceleration. t = 30 s t = 12s t = 0 x (m) 0 200 400
