An electron moving along x axis with a constant speed of v = 5x10^6 m/s i enters the region of a uniform electric field of E = 150 N/C j. What is the verticle displacement y of the electron 4 ns later?
A 0.300 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.750m/s when it makes a head-on collision with a stationary 0.150 kg glider, Find the final kinetic energy of first and second glider
A dynamite blast at a quarry launches a rock straight upward, and later it is rising at a rate of 15m/s. Assuming air resistance has no effect on the rock, calculate the total time the rock is in the air.
