1a)Mary and John build a rectangular wooden board with
dimensions 4.5m by 5.5 m by 0.30m thick to use as a diving
platform. If they put in into the river, how far below the surface
will the bottom of the board lie? Density of wood is 550kg/m^3.
1b)If a planet has 3/5 the radius of Earth, what is its mass?
Assume gravity is same as earth.
