One Big Rotation Problem - Part 1
This problem is part of a larger rotation problem I made up
to help my friends study physics.
A solid metal wheel with a radius of 3.0 cm and a mass of
2.0 kg is released from rest from the top of a frictionless ramp, 4.0 m from
the ground. It takes 3.0 sec to roll to
the bottom of the ramp without slipping. Determine (a) The wheel’s moment of
inertia, (b) the final linear velocity, (c) the final angular velocity, (d) the
linear acceleration of the wheel, (e) the angular acceleration of the wheel (f)
the number of revolutions the wheel turns through, (g) the net torque on the
wheel, (h) the distance along the ramp that the wheel travels, and (i) the
angle of incline of the ramp in degrees.
A complete walkthrough of the problem can be seen in the
full post.
