A golf ball threw by a friend from a window of her apartment collides with a rock that you throw at the same moment at x=44.07m and y=13.63 m, and t=2.56 s. If the ball was dropped from a height of h=45.78 m, determine the initial velocity of the rock(write de x- and y- components).
Is the ball thrown or dropped from the window? If thrown, at what velocity and angle?
Is the rock thrown straight up, or at an angle, from some x-position?
