Homework Statement
Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 149 km long, 27.7 km wide, and 152 m thick. (a) How much heat in joules would be required to melt this iceberg (assumed to be at 0 °C) into liquid water at 0 °C? The density...

A solid aluminum sphere has a radius of 2.34 m and a temperature of 89.0 °C. The sphere is then completely immersed in a pool of water whose temperature is 22.3 °C. The sphere cools, while the water temperature remains nearly at 22.3 °C, because the pool is very large. The...
A 2.0-kg pistol fires a 1.0-kg bullet with a muzzle speed of 1000 m/s. The bullet then strikes a 10-kg wooden block resting on a horizontal frictionless surface. The block and the embedded bullet then slide across the surface.
A) what is the kinetic energy of the bullet as it travels toward the...
A satellite, mass of satellite=5850 kg, is in circular orbit of 4.1x10^5m above the surface of a planet, which has a radius of 4.15x10^6m. The period for the orbit is 2 hours.
A) calculate the tangential velocity of the satellite.
B) find the mass of the planet.
C) how much would the...
The vertical surface of a reservoir dam that is in contact with the water is 170 m wide and 10 m high. The air pressure is one atmosphere. Find the magnitude of the total force acting on this surface in a completely filled reservoir. (Hint: The pressure varies linearly with depth, so you must...
