A solid ball of mass 1.30 kg and diameter 19.0 cm is rotating about its diameter at 65.0 rev/min.
What is its kinetic energy?
Also, if an additional 2.60 J of energy are supplied to the rotational energy,
what is the new angular speed of the ball?
A proton of mass m undergoes a head-on elastic collision with a stationary carbon nucleus of mass 12m. The velocity of the proton is 395 m/s in the positive x direction. The velocity of the center of mass of the system is 30.38 m/s.
What is the velocity of the proton after the collision?
A baseball bat of length 1.05 cetimeters has a lenear density given by l=.950 + 1.050x^2/l^2 find the x cooridinate of the center of mass in centimeters.
How am I supposed to work this problem?
Heres the questions I haven't answered yet. For you're giggling pleasure. It might help you help me more. I'm still lost. I've only been working with all these terms and stuff for two weeks now so big words and symbols confuse me more

I've got a lot of home work to do still and my book has run out of formulas for the questions my Professor so kindly gave us.
I'm not the brightest crayon in the box, and I know you arn't here to do my home work for me. so I'm just asking for some formuals, or somewhere to find formuals to...
