Extracted text: QI/ Vo A loaded railroad car is rolling at a constant velocity when it couples with a spring and dashpot bumper system. After the coupling, the motion of the car is defined by the relation x= 60e are expressed in mm and seconds, respectively. Determine the position, the velocity and the acceleration of the railroad car when (a) t = 0, 4.8r sin16t where x and ↑ (b) t = 0.3 s. Solve only without explaining English words and mentioning my name (Murtaza Ali Qasim) Please do not forget my name, Professor
