A spring is used to stop a 32 kg metal sphere which is moving down a 30° incline, as shown in Figure Q2(a). The spring has a constant k = 33 kN/m and initially compressed 50 mm. Given that the velocity of the metal sphere is 5.5 m/s when it is 5 m from the spring and the friction can be neglected. (Gravity g = 9.81 m/s?) Q2. (a) Determine all the kinetic and potential energy components at the initial (i) and final position of the metal sphere. (Let the x be the additional compression of the spring). (ii) Calculate the maximum additional deformation of the spring requires to bring the metal sphere to rest. (iii) Determine after the metal sphere come into rest will it rebound upwards the slope or not? if can how much it will move up again the slope until it temporary at reset otherwise stated the reason why the metal sphere would stay at rest. 5.5m/s m=32kg 5m 30 Figure Q2(a)
2. A block of mass m=3 kg is sliding along a frictionless inclined surface that makes an angle of o = 30°with respect to the horizontal surface. At the lowest points of the inclined surface, a projectile is fired at a speed of v, = 12 m/s that makes an angle 8, = 45° with respect to the horizontal. Our aim of this problem is to find the time when the projectile will hit the block. e = 450 h = ? Ro= 10 m P= 30° x= ? (a) Find the time when the projectile hits the block. (Given, the initial distance between the block and the projectile along the inclined surface at t=0 is R, = 10 m as shown in the figure) Page 1 of 3 (b) Find the height h, where the projectile will hit the block. (c) Now assume that the projectile hits the block at its maximum range R along the inclined surface and the block is not sliding at all. Then find the maximum range along the inclined surface, Rmax = ?

A bullet (W₁ = 3.5 oz) with a is fired horizontally with a velocity v₁ = 1675 ft/sec into the block (W₂ = 5.7 lb) of soft wood initially at rest on the horizontal surface. The bullet emerges from the block with the velocity v₂ = 1280 ft/sec, and the block is observed to slide a distance of d = 7.3 ft before coming to rest. Determine the coefficient of kinetic friction μk between the block and the supporting surface. Answer: Uk= i W₁ W₂

. An object of mass 12 kg is suspended from a pulley which has a mass of 6 kg and a radius of rotation of 0.25 m. If at that time the pulley rotates with an angular velocity of 5 rad/s, we want to know that when the object moves down a distance of 2 m, then at what speed is the pulley rotating? If the friction force on the pulley bearing produces a moment of resistance of 2 N-m 12 kg 0.3 m
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)

2. A mass of 2 kg is placed on a bar at a distance of r = 1 m from the point 0. Initially, the bar is in a stationary state, as shown in the figure below. At t = 0, the bar starts a counter clockwise rotation around the point O at a constant angular acceleration of 1 rad/s?. It is known that the mass can stop on the bar without sliding until 0 = 30°. Based on these givens, please answer the following questions. a. What is the static friction coefficient between the mass and the bar? b. When the sliding starts, will the mass be moving towards the origin or away from the origin? 1 rad/s? 2 kg r = 1m
