baseball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 5.33 m/s. The rooftop is at height h = 27.7 meters above the ground. Use a coordinate system where upwards is positive, as indicated in the figure. Part A: Find the vertical component of the final velocity, vf,y, in meters per second, with which the ball hits the ground. Part B: If we wanted the baseball's final speed to be exactly 27.3 m/s, from what height, hnew, in meters, would we need to throw the it with
A baseball is thrown from a rooftop with an initial downward velocity of magnitude v0 = 5.33 m/s. The rooftop is at height h = 27.7 meters above the ground. Use a coordinate system where upwards is positive, as indicated in the figure.
Part A: Find the vertical component of the final velocity, vf,y, in meters per second, with which the ball hits the ground.
Part B: If we wanted the baseball's final speed to be exactly 27.3 m/s, from what height, hnew, in meters, would we need to throw the it with the same initial velocity?
Part C: If the height is fixed at 27.7 m, but we wanted the baseballs final speed to be 32.7 m/s, what would the vertical component, in meters per second, of the initial velocity, vi,y, need to be?
