Problem #1: (30 pts.) The collars shown slide on a frictionless rod. Each of the collars have different mass: ma = 16 kg, mp = 8kg, mc = 12kg. At the instant shown collars B and C are at rest and collar A has a velocity of 2 m/s, knowing that the coefficient of restitution between the collars is 0.5: a) Determine the velocity of collar C after A hits B and B hits C in m/s. b) How would...

Chapter 2, Problem 2/190 x Incorrect The rod of the fixed hydraulic cylinder is moving to the left with a constant speed VA = 48 mm/s. Determine the corresponding acceleration of slider B (positive if downward, negative if upward) when 5a = 420 mm. The length of the cord is 1075 mm, and the effects of the radius of the small pulley A may be neglected. 245 mm Answer: ag = 35.563 mm/s2

Two blocks are positioned on surfaces, each inclined at the same angle 45.6 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines, so the blocks can slide together. The mass of the black block is 4.10kg and the coefficient of kinetic friction for both blocks and inclines is μk 0.370. Assume static friction has been overcome and that everything can slide. A) What must...
