Review I Constants
A box of negligible mass rests at the left end of a 2.50 m,
29.0 kg plank (Figure 1). The width of the box is
75.0 cm, and sand is to be distributed uniformly
throughout it. The center of gravity of the nonuniform
plank is 50.0 cm from the right end.
Part A
What mass of sand should be put into the box so that the plank balances horizontally on a fulcrum placed just below
its midpoint?

A a paddle for a boat is constructed of a stick of length L and a "quartic" end piece. The end can be thought of as a uniform flat board of mass m that has been cut to form a quartic function given by y = x*, so that the length from the trough (i.e., the y 0 end of the function) to the tip is y = H. To simplify this a little, assume that the stick is massless. This paddle is stood vertically upward on the stick end and attached to a hinge on the floor so that it is free to rotate in the in/out of the page direction. When it is standing straight up that is an unstable equilibrium. A very small infinitesimal push is given to get the paddle moving and it swings downward under gravity (acceleration g). (a) When the paddle is standing vertically upward, what is the position of the center of mass of the paddle? (b) What is the moment of inertia of the paddle for rotations in/out of the page about an axis through the center of mass? (c) What is the angular velocity of the paddle just before…
