Q1. Consider a spring mass system given in Fig 1 with mass of 1kg attached to a spring with K=10. The motion is damped with C=6 and is being driven by a force given by 25 cos 4t . If the spring is released from rest, find the equation of displacement y(t). Note: You cannot use the direct formulas for constants in particular solution. Spring Mass r(t) Dashpot Fig. 1

VIII PSS 7.1 Interacting-Objects Problems 8 of 27 (> Constants | Periodic Table Learning Goal: To practice Problem-Solving Strategy 7.1 for interacting-objects problems. • Show important points in the motion with a sketch. You may want to give each object a separate coordinate system. Define symbols, list acceleration constraints, and identify what the problem is trying to find. Draw an interaction diagram to identify the forces on each object and all action/reaction pairs. • Draw a separate free-body diagram for each object showing only the forces acting on that object, not forces exerted by the object. Connect the force vectors of action/reaction pairs with dashed lines. A 1230 -kg car is pushing an out-of-gear 2140 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4440 N . The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 770 N ,…
