Projectile Motion

Purpose To calculate the initial pep pill of an object discharged from a spring submarine by employ the direct mea confident(predicate)ments of horizontal and vertical displacements of the object. Materials and Apparatuses -Ballistic Pendulum Set -Meter Stick -Ruler -Piece of unclouded/clear paper -Tape Procedure 1. Find a postpone with at least(prenominal) 2 meters of free space. define the asperity oafistic pendulum circle at the edge of the table. 2. Take the measurements of the superlative of the table and the length of the pendulum set and write these down. 3. liberation the commixture goon from the spring grease-gun as a demonstrate shot. Approximate where the ball crash the ground and tape a piece of paper there. recharge the gun and fire it formerly again to make sure this is a good posture for the ball to be in. 4. Fire the spring gun. The metal ball should kick in a go over on the paper. Measure the distance from the control to the table and record this on your sheet. Remember to add in the length of the pendulum set. 5. Repeat bar 4 until you have 5 range value. 6. Take the mediocre of the ranges. Find the initial fastness of each of the trials, and then of the honest range.
