A 200KeV electron (i.e., an electron having kinetic energy of 200KeV) collides with a 200KeV positron (a particle with opposite charge of electron but) moving in the opposite direction in a head-on collision. The electron-positron pair annihilate each other and emit two equal-energy photons. (a) Write the law of conservation of energy for this process putting in all appropriate values. (b) write the law of conservation of momentum for this process putting in all appropriate values.
A glider with mass m = 0.240 kg sits on a frictionless horizontal air track, connected to a spring with force constant k= 5.00 N/m. What must the initial displacement of the glider be if its maximum speed in the subsequent motion is to be 3.00 m/s
A gun shoots bullets that leave the muzzle with a speed of 205m/s. If a bullet is to hit a target 151m away at the level of the muzzle, the gun must be aimed at a point above target.
