Problem 2: You have been hired to design a family-friendly see-saw. Your design will
feature a uniform board (mass M = 13 kg, length L = 8 m) that can be moved so that
the pivot is a distance d from the center of the board. This will allow riders to achieve
static equilibrium even if they are of different mass, as most people are. You have
decided that each rider will be positioned so that his/her center of mass will be a
distance xoffset = 29 cm from the end of the board when seated as shown.
You have selected a child of mass m = 25 kg (shown on the right), and an adult of mass
n =4 times the mass of the child (shown on the left) to test out your prototype.

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
