Four moles of an ideal gas undergo a reversible isothermal expansion from volume V1 to volume V2 = 5V1 at temperature T = 400K.
a) Find the work done by the gas.
b) Find the entropy change of the gas. (J/deg).
c) If the expansion is reversible and adiabatic instead of isothermal, what is the entropy change of the gas? (J/deg).
A car is traveling along a straight road at a velocity of +31.0 m/s when its engine cuts out. For the next ten seconds, the car slows down, and its average acceleration is a1.
An Olympic basketball player shoots towards a basket that is 5.36m horizontally from her and 3.05m above the floor. The ball leaves her hand 1.83m above the floor at an angle of 45.0o above the horizontal. What initial speed must she give the ball so..
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.

Burning a pound of coal produces about 13,000 Btu of energy. How many megajoules of energy are produced by burning 4 pounds of coal?
The collar C is moving downward with an acceleration of 1 m/s2. At the instant shown, it has a speed of 2 m/s which gives links CB and AB an angular velocity ωAB = ωCB = 10 rad/s. Determine the angular accelerations of CB and AB at this instant.
A rope of negligible mass is wrapped around a 225 kg solid cylinder of radius 0.40 m. The cylinder is suspended some meters off the ground with its axis oriented horizontally, and turns on that axis without friction.
