Sample Problem 6: A team of engineering students designs a medium- size catapult which launches 8-lb steel spheres. The vo = 80 ft/sec fence launch speed is the launch angle is above the 8° 0 = 35° 6' 20 horizontal, and the launch position is 6 ft above ground level. The students use an athletic field with -100'- 30- 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

Question

a team of engineering students designs a medium-size catapult which launches 8-lb spheres. The launch speed is the launch angle is above the horizontal, and the launch position is 6 ft above ground level. the student use an athletic field with an adjoining slop 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

Sample Problem 6:
A team of engineering students designs a medium-
size catapult which launches 8-lb steel spheres. The
vo = 80 ft/sec
fence
launch speed is the launch angle is above the
0 = 35°
20
horizontal, and the launch position is 6 ft above
ground level. The students use an athletic field with
30-
100
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
