Projectile motion of a ball. Throw a ball a distance of 10 m or more. Launch the ball at an angle between about 30 and 60°. Use a baseball or a basketball or some other ball with enough weight so that air resistance won't affect the results very much. Do not use a foam ball or beach ball or any ball made of thin plastic, because these aren't heavy enough. Ask a friend to measure the time t from the moment you release the ball to the moment the ball hits the ground. Record t (in seconds) as the answer to part (a) of this problem. Also ask your friend to note the spot where the ball landed so that you can measure the horizontal displacement Ax of the ball. Record Ax (in meters) as the answer to part (b) of this problem. Calculate (to the nearest 0.1 m/s) (c) the horizontal component Uxo, (d) the vertical component Uyo, and (e) the magnitude vo of the initial velocity of the ball. (f) Calculate (to the nearest 1 *) the angle between the initial velocity and the horizontal direction. (g) Calculate (to the nearest 0.1 m) the maximum height h of the ball during its flight. In all of these calculations, ignore the difference in height between the position where the ball was released by your hand and the position where the ball hit the ground. Your results should agree with what you observed.
(a) Time in the air. 1 = Range: [1,20] (b) Distance traveled. Ax = m Range: [1, 100] (c) The horizontal component, Uxo, of the initial velocity. m/s (± 0.2 m/s) (d) The vertical component, U,o, of the initial velocity. m/s (± 0.2 m/s) (e) The magnitude of the initial velcotiy, Uo. m/s (± 0.2 m/s) (f) The angle, 0, between the initial velocity and the horizontal. degrees (±2 degrees) (g) Maximum height of the ball. m (± 0.2 m) S
