The pitcher in a softball game throws a ball with an initial velocity Vo of 108 km/h at an angle a with the horizontal. If the height of the ball at Point B is 0.6 m 0.68 m, determine (a) the angle a, (b) the angle O that the velocity of the ball at Point B forms with the horizontal.

A batter hits the baseball A with an initial velocity of v0 = 108 ft/sec directly toward fielder B at an angle of 23° to the horizontal; the initial position of the ball is 2.9 ft above ground level. Fielder B requires 0.47 sec to judge where the ball should be caught and begins moving to that position with constant speed. Because of great experience, fielder B chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. The catch position is the field location at which the ball altitude is 6.3 ft. Determine the velocity of the ball relative to the fielder at the instant the catch is made.

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.

3. A car A is traveling with a constant speed of 80 km/h due north, while car B is traveling with a constant speed of 100 km/h due east. Determine the velocity of car B relative to car A. 100 km/h 2 km E0 km/h
