A block released from rest at position A slides with negligible friction down an inclined track, around a vertical loop, and then along a horizontal portion of the track, as shown above. The block never leaves the track. After the block is released, in which of the following sequences of positions is the speed of the block ordered from fastest to slowest?

A block of mass 500 g is attached to a spring of spring constant 80 N/m as shown below. The other end of the spring is attached to a support while the mass rests on a rough surface with a coefficient of friction of 0.20 that is inclined at angle of 30∘. The block is pushed along the surface till the spring compresses by 10 cm and is then released from rest. (a) How much potential energy was stored in the block-spring-support system when the block was just released? (b) Determine the speed of the block when it crosses the point when the spring is neither compressed nor stretched. (c) Determine the position of the block where it just comes to rest on its way up the incline. (15 points)

Consider blocks m1 and m2, with m1 held at rest on a horizontal table (where the coefficient of kinetic friction between m1 and the table is μk ), and m2 held in place by a movable, massless, frictionless pulley to which it is attached via a massless cable. As shown in Figure 7, the rope attaching m1 is run across a massless, frictionless pulley affixed to the table, which is then threaded through the movable pulley to then attach to the ceiling. The system is released, and the blocks are observed to move out of rest. Consider analyzing the problem from the point at which the system is released from rest up to the point when m1 has displaced by an amount ℓ. Figure 7: Block 1 is held in place on a horizontal table (with friction) with an attached, massless rope running from it to an affixed pulley, and then threading through a movable pulley to then attach to the ceiling. The movable pulley is attached to a hanging Block 2 via a massless cable. The system is released and is seen to displace, with work considerations to be investigated up to the point when Block 1 displaces by an amount ℓ. (a) Determine the work done by each individual force acting on each individual block for the considered displacement. (b) Determine the speed of each block for the considered displacement.
