An electron moving at a speed of vi= 0.960c in the positivex direction collides with another electron at rest. After thecollision, one electron is observed to move with a speed of v1f= 0.956c at an angle of?1= 9.7?with the x axis.
(a) Use conservation of momentum to find the velocity (magnitudeand direction) of the second electron.
(b) Based only on the original data given in the problem, use conservation of energy to find the speed of the second electron.

I put a packing peanut on top of it, and it only took one rotation--or crank--to knock the material off from the machine and onto the ground. mass of the peanut=.001 kg, distance from the machine to the peanut=.0005m.
When resting, a person has a metabolic rate of about 6.16 x 105 joules per hour. The person is submerged neck-deep into a tub containing 2.51 x 103 kg of water at 24.3 °C. If the heat from the person goes only into the water, find the water temper..
