Two objects of mass m move in opposite directions toward each other. The green object moves at velocity v, and the blue object moves at velocity 2v. Which diagram correctly shows the direction and velocity for each of the objects after an elastic collision?
. The velocity of a mass attached to a spring is given by v = (1.5 cm/s) sin(ωt + π/2), ..... Which of the following is the motion of objects moving in two dimensions
