A mass less spring is between a 1 kilogram mass and a 3 kilogram mass but is not attached to either mass. Both masses are on a horizontal frictionless table. The 1 kilogram mass located on the left is held in place and the spring is compressed by pushing on the 3 kilogram mass which is on the right. The 3 kilogram mass is then released and moves off with speed of 10 m/s
Find the minimum work needed to compress the spring in this experiment.
The spring is compressed again exactly as above but this time both masses are released simultaneously, find the final velocity of each mass relative to the table after the masses are released.
A radioactive nucleus travels at a velocity 0.1c. When it decays it ejects an electron which has a velocity relative to the nucleus of 0.8c. Find the velocity of the electron as seen from the laboratory frame
A 5000 ohms resistor and a 50uF capacitor are connected in series at t=0 with a 6V battery. The capacitor is initially uncharged. What is the maximum charge stored on the capacitor
Carbon disulfide (CS2) has a vapor pressure of 300 Torr at room temperature (almost half of atmospheric pressure). estimate the average time between collisions that the gas is experiencing inside the test chamber

Two 7.0kg bowling balls, each with a radius of 0.17m, are in contact with one another. What is the gravitational attraction between the bowling balls
A hollow sphere of radius 0.35 m, with rotational inertia I = 0.032 kg m2 about a line through its center of mass, How much of this initial kinetic energy is rotational
In exercise physiology studies, it is sometimes important to determine the location of a person's center of mass. This determination can be done with the arrangement shown in the figure below. A light plank rests on two scales, which read Fg1 = 365 N..
A moving charge experiences the maximum possible magnetic force when moving in a magnetic field. What can you conclude about the angle that the charge's velocity makes with respect to the magnetic field? Explain
