8.) consider two balls rolling down an inclined plane. one ball has a moment of inertia I and the other has a moment of inertia 2I. both balls start from rest at the same height and have the same mass. which ball will reach the bottom of the inclined plane first?
a. the ball with a moment of inertia I
b. ball with a moment of inertia 2I
c. same time
d. it is impossible to tell with the given information
Homework Answers
PE = KE
mgh = 0.5mv^2 + 0.5Iw^2
ball having smaller moment of inertia , less energy is spent in rotating the ball which means greater translational velocity
hence ball with smaller moment of inertia will reach quickly
so option A) is the correct answer

A solid cylinder is released from rest and rolls without slipping down an inclined plane. A block with the same mass slides down another inclined plane, which is identical to the first inclined plane except that it is frictionless. If both the block and cylinder are released from the same height and at the same time, М. M o the cylinder will reach the bottom first. o the cylinder will reach the bottom with a greater kinetic energy, neither object...

Two spheres of equal mass M and equal radius R roll down an
inclined plane as shown in the figure. One sphere is solid and the
other is a hollow spherical shell. The plane makes an angle ? with
respect to the horizontal. The spheres are released simultaneously
from rest at the top of the inclined plane and they each roll down
the incline without slipping.
The total distance each sphere rolls down the ramp (the
hypotenuse) is d. There...

Two solid spheres simultaneously start rolling (from rest) down an incline. One sphere has twice the radius and twice the mass of the other. 1. Which reaches the bottom of the incline first? (answer: arrive at the same time) 2. Which has the greater speed there? (answer: same speed) 3. Which has the greater total kinetic energy at the bottom? (answer: the one with larger R) i already have the answer, please explain WHY, thank you
