The launch speed is v, = 80 ft/sec the launch angle is 0 = 35° above the horizontal, and the launch positionis 6 ft above ground level. The students use an athletic field with an adjoining slope topped by an 8-ft fence as shown. Determine: (a) the x-y coordinates of the point of first impact. (b) the time duration of the flight. (c) the maximum height h above the horizontal field attained by the ball. (d) the velocity (expressed as a vector) with which the projectile strikes the ground vo = 80 ft/sec fence 8' e = 35° 20 -100- 30
