Jack and Jill are in a boat 4 m long. The boat has mass 48 kg and its weight is uniformly distributed along its length. Jill (mass 30 kg) sits at one end and Jack (mass 45 kg) sits at the other end. The boat is in still water, not moving as children stay still. If Jack and Jill exchange their positions, by how much does the boat move? Ignore any resistance of the lake's water.

A 2.18-m-long diving board of mass 13.2 kg is 3.00 m above the water. It has two attachments holding it in place. One is located at the very back end of the board, and the other is 25.0 cm away from that end. (a) Assuming that the board has uniform density, find the force acting on each attachment. {435 N, upward, 565 N, downward} b) If a diver of mass 69.3 kg is standing on the front end, what are...

A nasty person puts a man m=60 kg into a cart m=100 kg, and
places the cart against a large spring with k=9000 N/m, compresses
the spring by d=1.75 m, then releases the cart. The man and cart
shoot down a horizontal track with coefficient of friction 0.10.
The track ends at the edge of an extremely deep abyss which is 4.0
m wide. The other side of the abyss is higher than the side of the
track by 5.0...
