A shot putter launches a 7.26 kg shot by pushing it to the right along a straight line of length 1.65 m and at an angle of 30.0° from the horizontal, accelerating the shot to the launch speed from its initial speed of 2.50 m/s (which is due to the athlete's preliminary motion). The shot leaves the hand at a height of 2.11 m and at an angle of 30.0°, and it lands at a horizontal distance of 15.9 m. What is the magnitude of the athlete's average force on the shot during the acceleration phase? (Hint: Treat the motion during the acceleration phase as though it were along a ramp at the given angle.)

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 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 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.
