Part 5 of 5 - An Arbitrary Point Your nal point is an arbitrary point where there are no Arbitrary Position simplications {D}. At this point, the pendulum bob is a distance 24 cm below the point around which the rod is turning. Start by writing the position of the bob at the point {D}. (a) what is the position at the point (D)? Faev +- 2 {b} what is the position at the point {D}? This will be used to nd the velocity. arrv (9: w- ..r i } Now use the position to look at the energy at this point. (c) Analyze the energetics. E 4 + E.-, +. = {d} Find the speed of the bob from the kinetic energy. weev (e) Find the velocity of the bob in physical form using the speed and position. 6.=.. (1-: r-x a (f) Find the velocity of the bob in mathematical form .30 = :| y + :| i Part 1 of 5 At Release You are investigating a pendulum with a bob of mass 150 g attached to the end of a rod of length 33 cm. You release it at a height 19 cm above the pivot point, the point around which the rod turns. Choose this pivot point the be your reference point (origin) For the problem. You will start by nding the energy at the initial point. This begins with finding the initial conditions, the initial position and the initial velocity of the pendulum. First nd these in mathematical form
