Block A (M = 10 kg) is released from rest and slides
down an initially frictionless ramp (θ= 30°, L = 10 m). It
then passes over a rough patch of ground (µk=
0.633 and d = 5m) before impacting block B. Block B
(m = 20 kg) is initially at rest and suspended by a rigid
bar of negligible mass and length R = 5m. The coefficient
of restitution during the impact is e = 0.75. Determine
the maximum...

1. (30 points) A 2-kg block A is pushed up against a spring compressing it a distance r-0.1 m (i.e., the spring is unattached to the block). The block is then released from rest and slides down the 20° incline u it strikes a 1-kg sphere B that is suspended from a 1-m inextensible rope.

A block of mass 800 kg is released from rest 2 m above the top of a 2400-kg pile to drive it into the soil. If the block rebounds to a height of 0.1 m after impact with the pile, calculate the coefficient of restitution.

A 0.200 kg block is released from rest at a height h= 1.25 m above the level portion of the track shown below. The track is rough between points A and B, but elsewhere it is frictionless. As the block traverses the 0.850 meters between points A and B, 0.490 J of energy is dissipated as thermal energy. The spring constant of the spring attached to the wall is 225 N/m 0.850 m Where does the block finally come to...

2. A 10-kg block is released from rest at point A, as shown below. It slides along a track that is frictionless except for a "sticky" part between points B and C. After its motion along the track, the block hits a spring with spring constant 1500 N/m. It compresses the spring 0.4 m before momentarily coming to rest. 3.00 m 6.00 m-. We have seen in class that when an object moves along a rough surface, the force of...
