1.If the ballistic pendulum (with ball inside) rises to aheight, h = 9.74 cm, what was the velocity,vf of the ball and pendulum at thestart of the swing?
(Use the formula at 7:20 of the video)
Choice #1: Convert h to meters. Choice #2: Use g = 980cm/s/s
Give your answer in cm/s to 3 significantfigures (no decimal places in this case).
2. You find the velocity at which the pendulum and ball beginthe swing to be 124 cm/s.
The mass, M, of the pendulum is: 182 grams
The mass, m, of the ball is: 65.9 grams.
What is the velocity of the ball (after launch but before ithits the pendulum)?
Give your answer in cm/s to 3 significant figures (no decimalplaces in this case).
