A small block with mass 0.0400 kg slides in a vertical circle of
radius 0.500 m on the inside of a circular track. During one of the
revolutions of the block, when the block is at the bottom of its
path, point A, the magnitude of the normal force exerted
on the block by the track has magnitude 4N . In this same
revolution, when the block reaches the top of its path, point
B, the magnitude of the normal force exerted on the block
has magnitude 0.660 N .
How much work was done on the block by friction during the motion
of the block from point A to point B?

In the figure, a small block of mass m = 0.121 kg slides down a
frictionless surface from an initial height of h = 0.850 m and then
sticks to a uniform vertical rod of mass M = 0.879 kg and length L
= 1.83 m. The rod pivots about point O through an angle θ before
momentarily stopping. Find θ (in degrees).

A box with mass 0.0325 kg moves in a vertical circle that has a
radius of 0.600 m on the inside of a circular track. When the box
is at the bottom of its path, point A, the magnitude of the normal
force exerted on the box by the track has magnitude 3.75 N. When
the box reaches the top of its path, point B, the magnitude of the
normal force exerted on the box has magnitude 0.665 N.

A block of mass m = 2.1 kg slides down a 36 ° inclined ramp that
has a height h = 3.1 m. At the bottom, it hits a block of mass M =
7.1 kg that is at rest on a horizontal surface. Assume a smooth
transition at the bottom of the ramp. If the collision is elastic
and friction can be ignored, determine the distance the mass m will
travel up the ramp after the collision.

A block with mass m =6.2 kg is hung from a vertical spring. When
the mass hangs in equilibrium, the spring stretches x = 0.22 m.
While at this equilibrium position, the mass is then given an
initial push downward at v = 4.6 m/s. The block oscillates on the
spring without friction.
