A projectile is launched at an angle of 60" to the horizontal from 6 it above the ground at an initial speed of 100 ft/sec. Assume the x-axis is horizontal, the positive y-axis is vertical (opposite g), the ground is horizontal, and only the gravitational force acts on the object. Answer parts a through d. a. Find the velocity and position vectors for t 2 0. The velocity vector is v(1) = ( The position vector is n(t) =(] b. Graph the trajectory. Choose the correct graph below. O A. O B. O C. Ay 200-H 200TY 200- 100- 100- 100- X X 200 400 200 400 200 400 c. Determine the time of flight and range of the object. The projectile remains in the air for seconds. (Round to two decimal places as needed.) The projectile travels| feet. (Round to two decimal places as needed.) d. Determine the maximum height of the object. The maximum height of the object is|feet. (Round to two decimal places as needed.)
