- Two objects are connected by a light string passing over a light, frictionless pulley as shown in the figure below. The object of mass m₁ kg is released from rest at a height h = 5.60 m above the table. = 7.00 m2 m1 (a) Using the isolated system model, determine the speed of the object of mass m2 3.00 kg just as the 7.00-kg object hits the table. m/s (b) Find the maximum height above the table to which the 3.00-kg object rises. mTwo objects (m, = 4.50 kg and m, = 3.30 kg) are connected by a light string passing over a light, frictionless pulley as in the figure below. The 4.50-kg object is released from rest at a point h = 4.00 m above the table. (a) Determine the speed of each object when the two pass each other. m/s (b) Determine the speed of each object at the moment the 4.50-kg object hits the table. m/s (c) How much higher does the 3.30-kg object travel after the 4.50-kg object hits the table? Need Help? Read ItTwo rigid bodies, A and B, both 1 kg in mass, are connected by a linear spring with a spring constant of 0.2 N/m. Initially, the spring is unstretched and the bodies are at rest. If multiple forces and moments are applied to the two bodies that result in the speed of body A increasing to 10 m/s, the speed of body B increasing to 4 m/s, and the stretch of the spring increasing by 10 m, then -20 Nm of work was done by the spring on the body A, B system.

True False
- The balls A and B in the figure are attached to stiff rods of negligible weight. Ball A is released from rest and allowed to strike B. If the coefficient of restitution is 0.6, determine the angle through which ball B will swing. If the impact lasts for 0.01 s, also find the average impact force. 10 ft 10' 60° Ih A WA 30lb b 8 ft B We-20lbWhen landing from a vertical leap, a 549 N dancer decreases her vertical velocity from -5.9 m/s to -1.23 m/s, while lowering her center of mass a distance of 0.18 m over 0.04 s.

Realizing that he could not drive up a 30°, ice-covered hill because there was no friction, Sir Isaac Newton had stopped his cart, of total mass 500 kg, at the bottom. He was struck in the rear by a London stage coach, of total mass 1500 kg. trav- elling at 20 m/s. The two vehicles stuck together, with nothing breaking loose, and slid up the hill in a straight line. How far up the slope did the wreckage get before coming to rest? (SIN '70)
