- 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…Calculate the following: Cart A has a mass of 3 kg and is traveling at 5 m/s to the right. 1.

- Get the Gizmo ready: • Click Reset. Turn on Center of mass trail. • Move the blue puck to point (-4.0, -6.0). Set its Initial velocity to v = 3.00i + 6.00j. • Move the gold puck to point (4.0, -6.0). Set its Initial velocity to v = 3.00i + 6.00j. Activity C: Center of mass Introduction: Suppose you tried to balance a hammer on one finger. If you placed your finger halfway down the handle, the hammer would fall because the head is much heavier than the rest of the hammer. Instead, you would have to place your finger near the head to balance the hammer perfectly. The point where an object balances is called its center of mass. Question: How can you find the center of mass of a system? 1. Identify: The center of mass for the system of two pucks is where the balancing point would be if a weightless rod connected the pucks. Set the mass of both pucks to 5.0 kg. What do you think are the coordinates of the center of mass of the two pucks? 2. Compare: Click Play.

Don't type on the website it's hard to understand, I would appreciate if you put a picture of how you were doing it. A 0.500 kg block is released from rest at the top of a frictionlesstrack 2.50 m above the top of the table. It then collides elasticallywith a 1.00 kg mass that is initially at rest on the table. (a)Determine the speeds of the two masses just after the collision. (b)How high up the track does the 0.500-Kg mass travel back after thecollision? [a) 2.3 m/s, 4.7 m/s, b) 0.28 m]7.
