What was the mass of the ice cube taken from the freezer
A cube of ice is taken from the freezer at -6.3 and placed in a 106 aluminum calorimeter filled with 304 of water at room temperature of 20.0 . The final situation is observed to be all water at 17.0. What was the mass of the ice cube?

A 20.0 rock slides on a rough horizontal surface at 9.00 and eventually stops due to friction. The coefficient of kinetic friction between the rock and the surface is 0.200.
If the coefficient of kinetic friction between the player and the ground is 0.44, how far does the player slide before coming to rest?
Monochromatic light of variable wavelength is incident normally on a thin sheet of plastic film in air. The reflected light is a maximum only for 482.9 and 676.0 in the visible spectrum. What is the minimum thickness of the film ?
In a head-on collision, a car stops in 0.27 from a speed of 12 . The driver has a mass of 76 , and is, fortunately, tightly strapped into his seat. What force is applied to the driver by his seat belt during that fraction of a second?
a) Determine the acceleration of the block when x=.400m b) Describe the general behavior of the acceleration as the block slides from a location where x is large to x=0. c) Find the maximum value of the acceleration and the position x for which it
Two trains, each having a speed of 28 km/h, are headed at each other on the same straight track. A bird that can fly 56 km/h flies off the front of one train when they are 56 km apart and heads directly for the other train. On reaching the other
The tension in the string is 27 N. (a) What is the wave speed? (b) Find the linear density of this string in grams per meter.
A 45-N crate is suspended from the left end of a plank. The plank weighs 21 N, but it is not uniform, so its center of gravity does not lie halfway between the two ends.
3.60×1023 nitrogen molecules collide with a 18.0 wall each second. Assume that the molecules all travel with a speed of 410 and strike the wall head on. What is the pressure on the wall?
Suppose the space shuttle is in orbit 460 km from the Earth's surface, and circles the Earth about once every 93.8 minutes. Find the centripetal acceleration of the space shuttle in its orbit. Express your answer in terms of g, the gravitational
