The projectile is a steel ball, which is fired into a stationary, hollow pendulum bob suspended by a rod. After the ball and pendulum "collide", the pendulum and ball swing upward as one object and stop. pendulum cone bearing screw bell zatche bob ball C. M. latch spin sping ind cata an bell pawn trigger Instructions 1. Watch a demo of this experiment here: https://youtu.be/dBAi74A8Td8. 2. Assume the ball is fired into the pendulum 10 times. The angle for each trial is in the data table below. Determine the average angle. 3. Using the average angle, calculate the change in height of the ball/pendulum. 4. Using Conservation of Mechanical Energy, calculate the velocity of the ball/pendulum after the collision. S. Using Conservation of Linear Momentum, calculate the initial (muzzle) velocity of the ball. 6. Determine if the collision between the ball and the pendulum elastic or inelastic. Prove your answer by calculating the kinetic energy of the system before and after the collision.Data MPENDULUM = 140.2 g MBALL = 57.4 g LPENDULUM (to center of mass of ball) = 30.6 cm Trial # Angle (degrees) 1 48 2 50 3 51 4 54 5 48 6 49 7 55 8 52 9 53 10 51 Submission Submit the one page RESULTS Table (blank table provided) and all calculations.
