2. Oliver throws a ball at a 45.0 angle above the horizontal from the top of a building 150.0 m high. The ball strikes the ground at a point 65.0 m horizontally away from and below the point of release. TAKE UP AS POSITIVE. Box your answers but also put the final rounded answers in the boxes below. If you don't print the exam create the boxes at the bottom of the page. (a) Sketch the motion and label. (b) What is the time of flight? (c) What is the launch velocity? (d) With what velocity will the ball hit the ground (magnitude and directions)
