A spherical object has a(n) 54.4 m diameter.(adsbygoogle = window.adsbygoogle || []).push({});

Its moment of inertia about a diameter is

I = fMR^2, where M is its mass, R is its

radius, and f = 0.302.

The acceleration of gravity is 9.8 m/s^2

Starting from rest, how long will it take this

object to roll, without slipping, 10.88 m down

an incline that makes an angle of 35.1 degrees with

the horizontal? Answer in units of s.

How does I figure this out without a given mass? Does it cancel out in the calculation?

An approach to this and concepts involved in solving this would help greatly.

I don't know, I don't like moment of interia nor torque. :(

I have my final exam tomorrow, help is greatly needed and much appreciated.
