A disk is placed at the top of a ramp. When released, the disk rolls down the ramp. Point P is allowed to freely slide along a rail that ranges from the center of the disk to the edge. Find the acceleration of Point P with respect to a fixed frame using two methods: Taking the derivative of the position vector with respect to a fixed frame, A Using the magic formula. Assume the distance from the center of the disk to point P is R and the distance from the center of the disk to the origin is L.

Next two questions: We have a ring with radius R = 3 m with linear charge density λ = 50 μC/m. We have a point charge q = 80 μC that moves along the z-axis through the center of the ring. Point S is zS = 16 meters above the center, and point P is zP = 2 meters above the center. Remember that the electric field along the z-axis above a ring is E→ring = 2πkλRz(z2+R2)3/2 z^Change in potential energy from a ring 1 point Find the change in energy from point S to point P.

Block A and Block B are initially at rest, with Block A on top of a floor inclined 30∘ from the horizontal, and Block B resting on top of Block A. The mass of Block A is 40.0 kg, and the mass of Block B is 15.0 kg. The friction between Block A and the inclined floor is negligible. A force P is applied to Block A, as shown in the figure. It was observed that when P exceeds 500 N, Block B slips with respect to Block A. [25%] Determine the acceleration of Block A when P is equal to 500 N.

A rectangular block has its upper right corner carved out. The carved out portion is a quarter of a cylinder, yielding a circular slope of radius R. The remaining block has a mass M. A small bead of mass m is placed at the top of the slope. All contact surfaces are frictionless. Both the small bead and the block are initially at rest, and the bead slides down from the top of the circular slope. (a) Find the displacement of the block, i. e the distance and direction of its movement, when the small bead slides to the bottom of the circular slope and is just about to leave the block. (b) Find the speed of the small bead with respect to the ground when it reaches the bottom of the circular slope.
