A photon with an initial wavelength of 1.150×10-11 m Compton scatters from an electron which is initially at rest. The photon scatters at an angle of 180° (straight back), and the wavelength of the scattered photon is 1.636×10-11 m.
1. What is the magnitude of the momentum of the incoming photon?
2. What is the magnitude of the momentum of the outgoing photon?
3. What is the magnitude of the momentum of the electron after the collision?
4. What is the energy of the incoming photon?
5. What is the energy of the outgoing photon?
6. What is the kinetic energy of the scattered electron?
In extremely cold weather conditions where the inside thermostat is set to 27 C and the outside temperature is -20 C, your 1200 square ft house might lose heat through the walls at a rate of 4000 W. How much energy might you lose in one week?
Compute the magnitude of the average acceleration
A double speed trap is set up on a freeway. One police cruiser is hidden behind a billboard, and another is some distance away under a bridge. As a sedan passes by the first cruiser, its speed is measured to be 99.7 mph.
A 54.00 kg pole vaulter running at 10 m/s vaults over the bar. Her speed while she is above the bar is 1.0 m/s. Avoid air resistance, in addition to any energy absorbed by the pole, and determine her altitude as she crosses the bar.

The centers of a 10kg lead ball and a 90g lead ball are separated by 8.0cm. What is the ratio of this gravitational force to the weight of the 90g ball
even as Jo moves off in the opposite direction at a speed of 1.27m/s. assuming that friction is negligible, find out Al's mass.
A generating station is producing 2.00 106 W of power that is to be sent to a small town located 8.0 km away. Find the power used to heat the wires if the power is transmitted at 1300 V
A crate of 30.2- tools rests on a horizontal floor. You exert a regularly increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 319. After that you must reduce your push to 227 to keep it moving at a..
