A solid sphere with radius R = 4.00 cm has uniform density and mass m = 1.88 kg. It is released from rest at the top of an incline as shown. The coefficients of friction between the sphere and the slope are: μs = 0.50 and μk = 0.30. a) Find the linear acceleration of the sphere down the slope using Newton's 2nd law (hint: look at linear & rotational equations, since rolling uses both kinds of motion). b) What torque is produced by the frictional force? c) What is the angular velocity of the sphere when it reaches the bottom of the slope?

As shown in Figure 3(a), a wooden block B with mass mB = 2.4 kg on a rough inclined plane is connected to a massless spring ( k = 160 N/m ) by a massless cord passing over a pulley P of radius R = 0.25 m and mass Mp = 0.60 kg. The angle of the inclined plane is θ = 37∘ and the coefficients of static and kinetic frictions are μs = 0.35 and μk = 0.30 respectively. The frictional force at the axle of the pulley is negligible. The pulley can be regarded as a solid disk. (a) The system is at rest and in this case, block B is on the verge of sliding down. Figure 3(a) i. Indicate (with labeled arrows) the forces acting on the pulley and the block. ii. Calculate the tension in the string and the extension of the spring. (You can assume that the tensions in the cord on either side of the pulley P are the same for this part.) (b) As shown in Figure 3(b), another wooden block A of mass mA = 1.2 kg made of the same material as block B is released from rest. It slides down a distance l down the rough inclined plane and collides with block B. The two blocks stick together and move down the incline with a common velocity v = 0.80 m/s immediately after collision and the pulley rotates. The cord does not stretch and does not slip on the pulley. Figure 3(b) i. Determine the distance l. ii. Determine the acceleration of the two blocks at the moment they move down together and the pulley starts to rotate. iii. Determine how much further down the slope the two blocks move together after they collide before the two blocks come to a momentary rest.

A solid sphere with a mass of M = 1.00 kilogram and a radius of R = 6 centimeters starts at rest and rolls down a ramp that is 1.00 meter long and makes a 30∘ angle with the horizontal. The ramp connects with a horizontal track where a second, identical ball is located 1.00 meter away from the junction of the two sections. The two spheres collide. The rotational inertia for a solid sphere is I = 25 MR2. Show complete work for all answers. Assume that friction is negligible. a. Determine the time that elapses between the release of the sphere at the top of the ramp and the collision between the two spheres. b. Determine the angular momentum (both magnitude and direction) of the sphere when it has reached the bottom of the ramp. c. Calculate the linear velocity of the center of mass of the system consisting of both spheres after the collision.

A small rock with mass 0.26 kg is released from rest at point A, which is at the top edge of a large, hemispherical bowl with radius R = 0.48 m (Figure 1). Assume that the size of the rock is small compared to R, so that the rock can be treated as a particle, and assume that the rock slides rather than rolls. The work done by friction on the rock when it moves from point A to point B at the bottom of the bowl has magnitude 0.22 J.
