Suppose that a particle of mass m1 approaches a stationary mass m2 and that m2 > m1.
a) Describe the velocity of m2 after an elastic collision--that is, one in which both momentum and kinetic energy are conserved. Justify the answer mathematically.
b) What is the approximate momentum of m1...
I looked in the physics book and couldn't find any similar examples. Maybe someone can tell me how to go about this problem:
A picture it hanging on a nail. The tension in each string segment which is holding up the picture is 3.5 N. The string forms a 45 degree angle on the two top...
