A boy wants to throw a water balloon from a roof deck and hit the far side of the street below. He throws the ball at 6 m/s at an angle of 45° to the horizontal. If vboy = 0, what is the maximum height, h, reached by the balloon above the street? h = 6.28 m B. h = 5.3 m h = 4.92 m D. h = 5.28 m This time, suppose the boy gets a running start, vboy = 5 m/s toward the street. What is the speed of the balloon, vballoon, when it hits the street? vballoon = 9.9 m/s B. vballoon = 10.8 m/s vballoon = 11.6 m/s D. vballoon = 12.4 m/s
