\f\fProcedure: 1. Shoot ball into pendulum an casure / . Repeat 6 times and record average value. It should be measured between the base and the center of gravity point on the pendulum (s) Calculate h using h hinz (See figure below) cm Results Shot # hi (cm) 6.1 15.9 14.3 16.2 -10 16 15.8 AVG 2. Measure the mass of the ball (m). Remove the pendulum from the base and measure its mass as well. (M). m 50 M= g 3. Calculate the velocity (V) of the system after the collision using equation (8) Use g - 980 cm/$2 and mass in grams. cm/s 4. Use equation (6) to calculate the initial velocity of the ball (v) before the collision. cm/s Measure the height of the ball above the floor (y) 357 cm 6. Calculate the distance the ball will travel using the equation: x =v 2x (Derived from Freely Falling body kinematics) 9 - 980 com / 52 Xcalc cm 7. Place a coin on the floor corresponding to Xcalc and shoot the ball six times. Record the six distances traveled in the table below. Calculate the average distance and record it as Xexp. Xexp = cm Results 8. Calculate the experimental error Trial # Xexp (cm) error = % DWNH 9 . Reassemble the pendulum
