Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy. It is the very latest in home safety and is so easy to use! (Attatched Figure) If your building is on fire, simply reach out and grab the cord on the OyOy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass of M = 93.5 kg and is shaped like a cylinder of radius R = 0.950 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0840 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Rotation-OyOy-Energy (Figure) We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 72.0 kg is using the OyOy and begins his decent from an initial height of y0 = 13.70 meters. Determine…

Force After they are finished swinging, Tyler and Kelly decide to rollerskate. Theycome to a hill that is inclined at 8.58. Tyler pushes Kelly halfway up the hill and thenholds her there (Figure 14). If Kelly weighs 58.0 pounds, find the magnitude of the force Tyler must push with to keep Kelly from rolling down the hill. (We are assum-ing that the rollerskates make the hill into a frictionless surface so that the only force keeping Kelly from rolling backwards down the hill is the force Tyler is pushing with.)

1. A pulley device is used to hurl projectiles from a ramp (mk = 0.26) as ilustrated in the diagram. The 5.0-kg mass is accelerated from rest at the bottorm of the 4.0 m long ramp by a falling 20.0-kg mass suspended over a frictionless pulley. Just as the 5.0-kg mass reaches the top of the ramp, it detaches from the rope (neglect the mass of the rope) and becomes projected from the ramp. 4.0m M0.26 50kg 30 60m 20.0kg a.
