calculator to check yourself. The Formula Sheet in in the back of the exam. Good luck. A ball is thrown off a building. The initial velocity is 11 m s"at an angle of 443 from the horizontal. If the ball is in the air for 9.2 s, how tall is the building? How far away does the ball land from the building? 1: lims VX : 11/cos (44 ) : 7.91 mm = 440 Vy : 11 sin ( 44 ) = 7.64 m 4 4 = 9.25 1-9.31 1/4 17, 104 # 7
