5. A motor is using a large pulley to pull a crate with a mass of m= 200 kg up a 30 degree incline. The pulley has a mass of m = 50 kg, a radius of r = 0.5 m and a radius of gyration of ko = 0.25 m. The motor supplies a torque of M = (500 +1500) N*m to the pulley. If the crate starts from rest and the coefficient of kinetic friction between the crate and ground is µ = 0.2 (assume the crate immediately starts moving, so no static friction analysis needed). Determine the speed of the crate after it travels 4m. M 777 30°

QUESTION 14 The collar of mass m = 77 kg in Figure Q14 slides outwards with an initial radial velocity vo = 0.58 m-s-1 from zero initial radial position (see dashed box) along a smooth rotating shaft (see unit vector ur). The shaft rotates with constant angular speed of w = 2 rad-s-1. Determine the magnitude of the constant force F (N) that needs to be applied in the radial direction (pointing towards the centre of the shaft) in order to decelerate the collar to zero radial velocity the moment when the collar reaches a radial position r = 0.19 m. Consider motion in a horizontal plane, such that gravity can be ignored. Provide only the numerical value (in Newtons) to zero decimal places and do not include the units in the answer box.

Question 2 A car has a mass of 4 Mg and the center of mass at G = 400mm from the ground. The front wheels are 1.3 m and rear wheels are 0.8 m from the centre of gravity. Coefficient of kinetic friction between the wheels and the road is 0.2. Determine the acceleration if the rear driving wheels are always slipping and the front wheels are free to rotate. Neglect the mass of the wheels.
Problem #4) The extremities of a 4-ft rod weighing 50lb (1.5528slugs) can move freely and with no friction along two straight tracks. The rod is released with no velocity from the position shown, resulting in the rod to slide down the incline. The angular acceleration of the rod is a = +2.30k rad/s² and the linear acceleration at point A is 12.5674ft/s² to the right. Determine (a) ao, the linear acceleration at point G, and (b) RA and RB, the normal reaction forces at point A and B.
