When Meagan strikes her drum, the skin of the drum moves. The kinetic energy of the skin is converted to sound energy. Which statement best explains why all of the kinetic
energy is NOT converted to sound energy?
Friction slows the movement of the drum skin.
The kinetic energy is converted to potential energy.
Some of the kinetic energy is lost as heat.
The skin of the drum absorbs kinetic energy.

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
