a ball moving at 5m/s strikes a stationary ball of the same mass
the first ball moves at an angle of 30 degrees relative to th origional line of motion
the second ball moves at an angle of 90 degrees with respect to the final path of the first ball
find the velocity (magnitude and direction) of the second ball after contact
is this elastic or inelastic
explain and show work plz

Setup: We are rolling two dice. We know at least one of the dice shows a six? What is the probability that the sum of the two rolls is 12?

Why is the answer 1/11?

Thanks,
Kevin

I'm taking a Physics class this year, but I've become really lost in our current chapter. Before I request aid from the teacher, I was wondering how well some of you can help me. What is centripetal acceleration? How does it work? How is it different from tangential (linear) acceleration? What are the varibles connected to it (like alpha "a") and what they represent? What are the formulas used to find things in Centripetal acceleration? Can you give me a sample problem, with the answer to be found below it?
