students designs a medium size catapult which launches 8 kg steel spheres. The launch speed is vo = 45 m/sec, the launch angle is = 35° above the horizontal, and the launch position is 6 m above ground level as shown in Figure-3. The students use an athletic field with an adjoining slope topped by an 8 m fence as shown in the Figure, which is 130 m away from the releasing point of steel spheres. Neglect the air resistance for the following calculations. y vo = 45 m/sec fence 8m 0 = 35° 20m 6m 100'm 30 m a) Determine steel sphere's time duration tf of the flight. b) Calculate the x-y coordinates of the point of first impact of the steel sphere.
