A ball with a mass of 0.580 is initially at rest. It is struck by a second ball having a mass of 0.415 , initially moving with a velocity of 0.260 toward the right along the axis. After the collision, the 0.415 ball has a velocity of 0.205 at an angle of 36.9above the axis in the first quadrant. Both balls move on a frictionless, horizontal surface. What is the magnitude of the velocity of the 0.580 ball after the collision? What is the direction of the velocity of the 0.580 ball after the collision (this is in degrees below the axis in the forth quadrant)? What is the change in the total kinetic energy of the two balls as a result of the collision?

A red laser, with a wavelength of 640 nm, shines on a diffraction grating with a grating spacing of 500 lines/mm. The resulting diffraction pattern is observed on a screen 1.00 meters away from the grating.
Although an ideal voltmeter has an infinite internal resistance, this theoretical ideal is usually not met in practice. The voltmeter has an internal resistance of 8 x 10^9 Ohms and is used to measure the voltage across the resistor R2.
