A container contains 1 mole of an ideal gas with Cp = 29.1 J/mol K and Cv = 20.8 J/mol K.  How much heat is required to increase the temperatuer by 500K while keeping the volume constant?

A 1 kg block is pushed against a spring attached to the wall.  The spring has a spring constant of 100N/m and is originally compressed 0.1 meters.  After letting go, the spring pushes the block along a frictionless surface.  What is the block’s velocity after leaving the spring?

A brake pad applies a friction force of 12 N acting tangent to a wheel spinning at 60 rpm.  The wheel has a radius of 0.1 m and a moment of inertia of .05 kg m2. What is the angular acceleration caused by friction?

An ideal gas contains atoms with a mass of 30amu, what is the average speed of the gas molecules when the temperature is 300K?

A ball is thrown up in the air and later caught.  Which graph best describes velocity versus time?

The velocity vector of an object points left while the acceleration vector points right.  Which statement describes its motion?

You decide to attach a large 10,000N rocket motor to your 1000kg car.  If the engine burns for 4 seconds, what will be your car’s velocity if it started from rest?  The car is moving horizontally.  Assume that the rocket thrust is the net horizontal force.

In a thermodynamic cycle, which two must be true?

Water flows through a horizontal pipe that narrows to ¼ the original area.  If the water originally had a velocity of 4m/s, what is the velocity in the narrow part of the tube?

A planet has a mass 300 times that of Earth and a radius of 12 times its radius.  What is the acceleration due to gravity due on its surface?  There are a couple ways to do this.  For the longer way, you need to know the mass of the Earth is 5.97*1024 kg and the radius of the Earth is 6,371,000 meters.  G = 6.67*10-11 N m2/kg
