An object with mass M is sliding along a horizontal, frictionless surface with a velocity of V. It then slides up a hill that is 15 degrees above the horizontal. The object travels a distance D parallel to the surface of the hill before coming to rest.
If the hill does have friction, what is the work down by friction. Give your answer in terms of M, V, D, g, and Constants.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm
