Q10 A hollow sphere and a hoop of the same mass and radius are released at the same time at the top of an inclined plane. If both are uniform, (1) Which one reaches the bottom of the incline first if there is no slipping? (2) A uniform hollow sphere of mass 120 kg and radius 1.7 m starts from rest and rolls without slipping dow an inclined plane of vertical height 5.3 m. What is the translational speed of...
A uniform drum of radius R and mass M rolls without slipping down a plane inclined at angle . Find its acceleration along the plane (translational acceleration). The moment of inertia of the drum about its axis through the center is I = MR^2/2 .
2. Rolling down the hill (a) A solid cylinder of mass 1.0 kg and radius 10 cm starts from rest and rolls without slipping down a 1.0 m-high inclined plane.

A uniform, solid sphere rolls without slipping along a floor, and then up a ramp inclined at 17º. It momentarily stops when it has rolled 0.85 m along the ramp. 1) Solve for an algebraic expression for the linear speed of the sphere. 2) What was the sphere's initial linear speed?
Question 13 (a) What does it mean to say that an object is dynamically balanced? How is this different to an object being statically balanced? [2 mark] b) A uniform solid cylinder of mass m- 2kg and diameter D 0.2m is resting against an inclined plane when it is struck by a 70g bullet. The cylinder is initially in contact with the plane at point A. The bullet was travelling horizontally at 350m/s and hits the cylinder at its midpoint....
