A ball is thrown from a rooftop with an initial downward velocity of magnitude vo = 4.9 m/s. The rooftop is a distance above the ground, h = 29 m. In this problem use a coordinate system in which upwards is positive. A: Find the vertical component of the velocity, vfy, in meters per second, with which the ball hits the ground. B: If we wanted the ball's final speed to be exactly 27.3 m/s, from what height, hnew (in meters), would we need to throw it with the same initial velocity? c: If the height is fixed at 29 m, but we wanted the ball's final speed to be 32.7 m/s, what would the vertical component of the initial velocity viy need to be, in meters per second?
