Need help in 15 minutes. ASAP. A 75-kg block is attached to a cable. The cable is then attached to a rotating assembly with a mass moment of inertia of 18 kg-m^2. The bearing friction applied at the rotating assembly equivalent to a couple of 45 N-m CCW. The block's downward speed is initially at 2 m/s. What is the total work done by the system after the rotating assembly has rotated 1.5 radians CW? What is the speed of the 75-kg block after the rotating assembly rotated 1.5 rad CW?
Consider a solid cylinder of mass 5 kg and radius 0.3 m on a surface with insufficient friction so that the cylinder will slip (with max friction force). The angle of the incline is 0 = 58 deg, and the coefficient of friction is u = 0.19. If the cylinder starts from rest, calculate the time required for the center of mass to travel a distance of 7 m along the incline. N mg

A cigarettes dispenser requires a south African five-rand (R5) coin with a mass of 9.5 g to dispense one cigarette with a mass of 0.2 g. The design of such a cigarette dispenser is based on a helical spring, of negligible mass, which is found to extend 0.1 mm under a mass of 0.2 g. The spring can support a total mass of a coin. As the customer place money on the dispenser, the spring and coin system displace vertically through 4 mm and release. 1.1. Provide a schematic representation of the mass and spring system. 1.2. Calculate the frequency of natural vibration of the dispenser. 1.3. Determine the velocity of the coin when it is 2 mm below its resting position.

A small object A of mass m = 0.22 kg is held against the vertical side of the rotating cylindrical container of radius r = 0.60 m by centrifugal action. If the coefficient of static friction between the object and the container is μ = 0.33, determine the minimum rotational rate = w of the container which will keep the object from slipping down the vertical side. cb=0 Answer: w= i A rad/s
