Suppose a horse leans against a wall as in Figure 5.35.
Calculate the force exerted on the wall assuming that force is
horizontal and using the data in the schematic representation of
the situation. Note that the force exerted on the wall is equal and
opposite to the force exerted on the horse, keeping it in
equilibrium. The total mass of the horse and rider is 675 kg. Take
the data to be accurate to three digits.

A wheel with a mass of 0.8·kg and a radius of 0.35·m is pulled
by a horizontal force applied at its center. The curb is 0.14·m
high.
a) What is the minimum force needed to just raise the wheel off
the ground?
b) Suppose the horizontal force you found in the previous part
is increased by 4.2·N. If you model the wheel as a simple hoop,
what is its initial angular acceleration as it starts to
rise off the ground?

A ladder whose length L is 12 m and mass m is 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground. The center of mass of the ladder is one-third of the way up the ladder. A fire fighter whose mass M is 72 kg climbs the ladder until his center of mass is halfway up. Assume the wall but not the ground is frictionless. What forces are exerted on...
