Q2: The 0.5-kg cylinder A is released from rest from the position shown and drops the distance h; = 0.8 m. It then collides with the 0.4-kg block B; the coeffi- cient of restitution is e = 0.8. Determine the maxi- mum downward displacement ks of block B. Negleet all friction and assume that block B is ini- tially held in place by a hidden mechanism until the collision begins. The two springs of modulus % = 400 N/m are initially unstretched, and the dis- tanced = 1.0m.
The cannon and support without a projectilehave a mass of 250 kg.

Neglect rolling resistance.Show the Free Body Diagram
The 600-kg bar B, originally at rest, is towed over a series of small rollers. The motor M is drawing in the cable at a rate of v = (0.3 t2) m/s, where t is in seconds. Determine the force in the cable when t = 2 s
The 4-kg box slides on the smooth surface and has a velocity of 15 m/s. If it strikes the smooth plate, which has a weight of 2 kg and is held in position by an unstretched spring of stiffness k = 600 N/m, determine the maximum compression imparted to the spring. Take e = 0.7 between the box and the plate.
Block A has a mass mA and is attached to a spring having a stiffness k and unstretched length l0. If another block B, having a mass mB, is pressed against A so that the spring deforms a distance d, determine the distance both blocks slide on the smooth surface before they begin to separate. What is their velocity at this instant?
The collar of mass m is released from rest while in position A and subsequently travels with negligible friction along the vertical-plane circular guide. Determine the magnitude of the normal force exerted by the guide on the collar (a) just before the collar passes point B, (b) just after the collar passes point B (i.e., the collar is now on the curved portion of the guide), (c) as the collar passes point C, and (d) just before the collar passes point D. Use the values m = 0.5 kg, R = 1.0 m, and k = 290 N/m. The unstretched length of the spring is 0.70R.

The bungee jumper, an 70-kg man, falls from the bridge at A with the bungee cord secured to his ankles. He falls 20 m before the 17-m length of elastic bungee cord begins to stretch. The 3 m of rope above the elastic cord has no appreciable stretch. The man is observed to drop a total of 44 m before being projected upward. Neglect any energy loss and calculate (a) the stiffness k of the bungee cord (increase in tension per meter of elongation), (b) the maxi-mum velocity vmax of the man during his fall, end (c) his maximum acceleration amax. Treat the man as a particle located at the end of the bungee cord.
