Find acceleration and tension fast please

Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo
spelled backwards). It is the very latest in home safety and so easy to use!
If your building is on fire, simply reach out and grab the cord on the OyOy and you will accelerate slowly and safely toward the ground.
The OyOy has a total mass M = 101.0 kg and is shaped like a cylinder of radius R = 0.830 meters. The secret to the operation of the
OyOy is its patented shaft whose radius is only r = 0.0905 meters. The cord is wound around the small shaft and this is the secret to
your low acceleration.
Outer Radius = R
Spindle Radius = r
Mass = M
Determine all the following:
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 = 85.0 kg is using the OyOy.
The FORMULA for the moment of Inertia: I =
T=?

The FORMULA for the relationship between a and a: a =
The acceleration of the customer: a =
The tension in the cord: T =

You kick a ball vertically from the ground and give it an initial velocity of = 30 m/s. Vi Find the height the ball reaches at the very top. You will need to do this using two different methods. Method 1: A. Use the velocity equation to find the time it takes to reach the top. B. Use the position equation to find the height (Y) that the ball reaches Method 2:C. Use conservation of energy to find the height that the ball reaches. D. Which method was easier?
Spring drive!context A block is placed at the end of a compressed spring (without being attached to it). We release the block, it is propelled towards a rough surface. What total distance (from its initial position) will the block travel before stopping? Information The mass of the block is known.The block is initially at rest.There is no friction up to a distance D.From a distance D, the ground becomes rough: the coefficient of kinetic friction is known.The spring constant is known.The initial compression of the spring is known. Schematization Represents the initial and final states of the system, identifying an upward y+ axis for the block. Modelization Creates a model for the distance traveled by the block, based on known parameters only. Then test your model with the following values: Block mass: 18.1 kg Distance before rough part (D): 3.4 m Kinetic coefficient of friction: 0.24 Spring constant (k): 84 N/m Initial spring compression: 0.5 m
