PROJECTILE MOTION AND REATIVE VELOCITIES REVIEW PROBLEMS PROBLEM 1 Brown University has a unique location for its field hockey field. The field is on top of one of the campus buildings. A field hockey ball traveling horizontally at 8 m/s gets through a hole in the fence. The building is 20 m high. A. What is the initial horizontal velocity? B. What is the initial vertical velocity? C. How long will it take the ball to reach the ground? D. How far away from the building does the ball land? What is the velocity of the ball in the vertical direction when it lands? What is the horizontal velocity of the ball when it lands? G. What is the total speed of the ball when it lands? H . What angle does the velocity vector make with the horizontal when it lands? As the ball falls, its horizontal speed its vertical speed and its total speed maldog PROBLEM 2 age sis Ithan to leswy grilisa girle A A soccer player kicks a stationary ball, giving it a speed of 14 m/s at an angle of 25 above the horizontal J.
