A yo-yo has a rotational inertia of 950 g cm^2 and a mass of 120 g. Its axle radius is 3.2 mm, and its string is 120 cm long. The yo-yo rolls from rest down to the end of the sting.

(a) What is the magnitude of its translational acceleration?

(b) How long does it take to reach the end of the string?

As it reaches the end of the string, what are its (c) translational speed, (d) translational kinetic energy, (e) rotational kinetic energy, and (f) rotational speed?

What equations did you use to solve this, and can you explain your answers?

A thin uniform rod is initially positioned in the vertical direction, with its lower end attached to a frictionless axis that is mounted on the floor. The rod has a length of 1.60m and is allowed to fall, starting from rest. Find the tangential speed of the free end of the rod, just before the rod hits the floor after rotating through 90.0o.


It is not just gravity acting on it? anyone?

I have few questions..

how can i explain the differences in the reaction rates..
and can H2O2 be broken down by catalysts other than thoses found in living systems..?
lastly, what's the difference between the rates of reaction with potato as compared to liver..?

well, for the last question, i know in liver there is a catalase..but what does it do..?does it make the reaction faster..?
