A projectile is launched at an angle of 60° to the horizontal from 6 ft 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≥ 0. The velocity vector is v(t) = ( The position vector is r(t) = b. Graph the trajectory. Choose the correct graph below. O A. 200- 200- vn 100- 400 100- 0 B. 200 200 c. Determine the time of flight and range of the object. The projectile remains in the air for 5.45 seconds. (Round to two decimal places as needed.) The projectile travels 272.52 feet. (Round to two decimal places as needed.) d. Determine the maximum height of the object. The maximum height of the object is 122.57 feet. (Round to two decimal places as needed.) 400 Q C. 200- 100- 0 y 200 400
