A ball is thrown into the air with an initial velocity of 15 m/s at an angle of 50° relative to the ground. Neglecting air friction... (a) How far above the point of release is the ball's maximum height? (b) How far away from the thrower is the ball when it returns to the height from which it was thrown? (c) What is the ball's velocity when it returns to the height from which it was thrown? Explain your answer two ways: (1) explain how you expect the x and y components of this final velocity to compare to the x and y components of the initial velocity, and (2) show the vector calculations for the change in velocity caused by the acceleration of gravity during the time interval that the ball is in the air.
