Show that the girl at A can throw the ball to the boy at B by launching it at equal angles measured up or down from a 45° inclination. If VA = 10 m/s, determine the range R if this value is 15°, i.e., θ1 = 45° -15° = 30° and  θ2 = 45° + 15° = 60°. Assume the ball is caught at the same elevation from which it is thrown.

The baseball player A hits the baseball at VA = 40 ft/s and  θA = 60° from the horizontal. When the ball is directly overhead of player B he begins to run under it. Determine the constant speed at which B must run and the distance d in order to make the catch at the same elevation at which the ball was hit.

A golfer hits the ball with an initial velocity of 160 ft / s, at an angle of 25 ° to the horizontal. If the field of play descends at an average angle of 5 °, determine the distance d between the golfer and point B where the ball first touches the field.

The football player at A throws the ball in the yo-z plane at a speed v = 47 ft/s and an angle = 60° with the horizontal. At the instant the ball is thrown, the player is at B and is running with constant speed along the line BC in order to catch it. (Figure 1) Figure Z 30 ft OA < offe B 20 ft 1 of 1 Part A Determine this speed, vµ, so that the player makes the catch at the same elevation from which the ball was thrown.
