Show that the moment of inertia of a spherical shell of radius R and mass M about an axis through
its centre is 2/3 MR2. Show also that the moment of inertia of a uniform solid sphere of radius R and

mass M is 2/5MR2. The spheres are allowed to roll (from rest), without slipping a distance L down
a plane inclined at a angle θ to the horizontal. Find expressions for the speeds of the spheres at the
bottom of the incline and show that ∆v/〈v〉 = 8.7% where ∆v is the difference in the speeds and 〈v〉 is

the mean of the two speeds. Which sphere has the larger speed?

Your driving time to work T (continuous random variable) is between 24 and 66 minutes if the day is sunny, and between 49 and 82 minutes if the day is rainy, with a uniform probability density function in the given range in each case.

Assume that a day is sunny with probability Ps = 0.64 and rainy with probability Pr = 1 -Ps.

Your distance to work is X = 50 kilometers. Let V be your average speed for the drive to work, measured in kilometers per minute:

V=T/X

Compute the value of the probability density function (PDF) of the average speed V at V = 0.67
