The two masses m₁ = 4kg and m₂ = 6kg are connected by a massless string passing through a massless pulley as shown in the figure below. If the system is
released from rest when m₁ is on the ground and m2 is h above the ground, m₂ hits the ground with a speed of v= 9.1m/s. Determine the heighth from where m₂
is released. Take g = 9.8m/s² and express your answer in units of m using one decimal place.

A raccoon is sitting on one end of the log and notice that there is an delicious apple just above
the other end of the log on the still water as shown on figure. The raccoon starts to walk along the
log of 10 meters length at a constant velocity of 0.1 m/s with respect to the log. Neglect its size. The
mass of the raccoon is m = 20 kg and the mass of the log is M = 90 kg. Depending on your choice of
method, you may answer (b) before (a). You should solve both methods (Center of Mass and
Conservation of Momentum).
a) As the raccoon is walking, what is the velocity of the log with respect to the shore?
b) When the raccoon reaches the opposite end of the log, how far is he horizontally from
the apple he desires?
1. A thin strip of metal of mass M is bent into a quarter circle with radius R. Relative to a
coordinate system where the center of the circle is at the origin, what is the position of its
center of mass, (Xem, yem)? The integrals you'll need to compute to find the center of mass are
given below. You answer should be symbolic, in terms of R (for example, 0.1R).

To do this, you throw a ball of mass mb at the two disks that are still rotating together with the same speed (just after they collide). You throw the ball at the disks, and the ball follows the following trajectory as viewed from above. The ball of mass mb approaches the disks at an angle θ with respect to the tangent line to the disk and rebounds at an angle ϕ with respect to the normal.
