A lump of putty (0.20 kg) hits a block (1.00 kg) at the bottom of a rough vertical loop that is 1.0 m in radius. After the collision, the putty/block combination slides through the loop. At the top of the loop, the combination has an apparent weight of 5.88 N. The coefficients of kinetic & static friction between the block and loop are 0.23 & 0.37 respectively and the work due to friction during the combination’s ascent is -17.34 J. Determine the speed of the putty/block combination at the top of the loop. Determine the speed of the combination at the bottom of the loop. Assuming that friction is much less than impact force, what was the speed the putty before the collision?

Gwen is baby-sitting for the Parker family. She takes 3-year old Allison to the neighborhood park and places her in the seat of the children's swing. Gwen pulls the 1.8-m long chain back to make a 26° angle with the vertical and lets 14-kg Allison (swing mass included) go. Assuming negligible friction and air resistance, determine Allison's speed at the lowest point in the trajectory.
A sledgehammer of mass m = 1.9 kg falls freely vertically downward from a height of h = 2.5 m at an initial speed of v = 6.5 m/s before striking a partially buried piling. After the blow the piling has moved d = 0.075 m deeper. How much force, in newtons, was applied to the piling? Assume all the energy goes towards driving the piling into the ground, and the force of the sledgehammer is constant over the distance d that the piling is driven into the ground. Note that you can ignore the change in potential energy of the piling itself. Further, because d is so small compared to h, you can also ignore the change in potential energy of the hammer as well as it moves distance d.
