You don't know the time it took to reach the final velocity. The displacement is negative. The initial velocity is not zero. 33% Part (b) If we wanted the ball's final speed to be exactly 27.3 m/s, from what height, new (in meters), would we need to throw it with the same initial velocity? à 33% Part (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 need to be, in meters per second? 1 Grade Summary Deductions Potential 100% Submissions Attempts remaining (0% per attempt detailed view 1 2 3 0%
(4%) Problem 13: A ball is thrown from a rooftop with an initial downward velocity of magnitude v = 3.4 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.
