Question 1
A solid sphere (radius
R, mass
M) rolls without slipping down an incline as shown in the figure. The linear acceleration of its center of mass is
◦
(5/7)g sin θ
◦
(3/5)g sin θ
◦
(2/3)g sin θ
◦
(1/2)g sin θ
◦
(4/5)g sin θ
Question 2
A solid sphere, spherical shell, solid cylinder and a cylindrical shell all have the same mass m and radius R. If they are all released from rest at the same elevation and roll without slipping, which reaches the bottom of an inclined plane first?
◦
solid sphere
◦
spherical shell
◦
solid cylinder
◦
cylindrical shell
◦
all take the same time
