Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block m, which is connected to block mg by a long, massless spring with spring constant k = 7000 N/m; see the figure. Each of blocks m2 and m3 has a mass of 5 kg. Before the collision, blocks m, and mg are stationary and the spring is relaxed. k m2 m3 Frictionless • For parts A, B and C assume that the collision of blocks mį and m2 is completely inelastic. (Because the spring is relaxed before the collision, block mg does not move at the instant of impact, therefore (m1 +m2) must move through a finite displacement before any force acts on mz and cause it to move.) For parts D and E assume that the collision of blocks m, and m, is elastic.

An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

A steel ball of mass M is held at a distance H above a massless rigid tabletop supported by undamped springs whose equivalent stiffness is K. If the ball is left to fall from rest on the tabletop. Deduce an expression for the velocity at which the ball will bounce back off the tabletop. On its way back, will the mass bounce back to its initial height? If it will not, where will the difference in energy go? Discuss mathematically! (Pls solve the question in detail with figure)

A block of mass m₁ is suspended from the ceiling with a spring k and damper b. Attached to the block is a massless rod of length L. Affixed to the end of the rod is a point-mass of mass m₂. Gravity is acting in the direction indicated in the figure. Use the energy method to set up the energy expression you would use to calculate the equations of motion for the system. Hint: be sure to decompose the velocity of the pendulum into horizontal and vertical components. DO NOT CALCULATE THE EQUATIONS OF MOTION, only setup the energy expression. x(t) b 7 m₁ e(t) (m₂
