1. On a planet where the gravitational acceleration is g=10 m/s², a solid cube of wood measuring one foot on each edge exerts a uniform pressure of 3048 Pa on a flat tabletop due to its weight. Find the wood's specific gravity and state whether it will float on water. One foot is 0.3048 m.

2. A crown is made of an alloy consisting of gold (19 g/cc) and copper (9 g/cc). It weights 35 N in air, and 32.5 N when submerged in water. What fraction of its volume is gold?

A planet has the same density as Earth but has a surface gravitational acceleration of nine times that of the Earth (a person would instantly black out if placed on the surface). What is the escape velocity from the planet? If the planet was in an orbit of 1 AU from a 1 M⊙ star, what is the maximum distance that a moon could orbit the planet?

A 12.7 g bullet is fired into a block of wood at 245 m/s. The block is attached to a spring constant of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass of the wooden block.

An object of 4 kg (assuming the acceleration of gravity g = 10 m / s2 ) suspended from a spring causes the spring to stretch 2 cm downwards. The object is moved 3 cm down from from its equilibrium position in the positive direction of movement, then it is released with speed zero initial. Assuming that there is no damping and that the object is under external force equal to: 20cos4(t) (N) a) Formulate the initial value problem that...

On a planet, the acceleration due to gravity is only 7.2 m/s2. A person living on that planet throws a football at 10 m/s at an angle of 48 degrees to the horizontal. The person is standing, so the ball launches from an initial height of 1.8 meters above the ground. (Ignore any air resistance here.) What maximum height from the ground would the ball reach? What would be the flight time before the ball gets back to the ground?

You are once again on the Pizza Planet of Alpha Centauri IV where the acceleration due to gravity is still gP = 9.12 m/s2 . Luigi is on one of the long, straight, moving walkways which has a constant velocity of 12.5 m/s, but he is late for an important engagement with Mario so is walking at a constant velocity of 5.50 m/s with respect to the moving walkway. You observe Luigi from an adjacent walkway that is moving at...
