Chapter , Problem 20AAE(choose chapter or problem)
Velocity after a ricochet A particle traveling in a straight line with constant velocity i+j-5k passes through the point (0, 0, 30) and hits the surface . The particle ricochets off the surface, the angle of reflection being equal to the angle of incidence. Assuming no loss of speed, what is the velocity of the particle after the ricochet? Simplify your answer.
