Problem 15: Block-Spring-Plate
A block of mass m is attached to
the top of a spring with spring
constant k. The bottom of the
spring is attached to a plate
of mass M , which rests on a
horizontal table. This problem
is based on a similar childs
toy, where
Problem 18: 2D Elastic Collision of Disks
A disk of radius r and mass m
is traveling to the right with a
speed v on a frictionless, horizontal surface. A second disk of
the same mass, but possibly different radius R, is a rest on the
surface, and the line

Problem 16: Power and Acceleration
At t = 0 a car of mass m located at x = 0 accelerates from
rest. We will consider the relationship between the acceleration
and the engine power. Note: The cars engine exerts a torque
(twisting force) on the wheels, whic
