Hello! I need help with this physics problem, I've some what attempted it and I need some feedback. ANY help would be awesome! 1. The problem statement, all variables and given/known data Two objects (A and B) of equal mass, undergo an elastic collision in deep space. Initially, B is at rest and A approaches at velocity v. The duration of contact is 2 seconds. (a) What is the velocity of object A after the collision (final velocity)? (b) What is the final velocity of B? (c) At what time is the kinetic energy of the two object system a minimum? (d) What has the kinetic energy been converted to? 2. Relevant equations 3. The attempt at a solution (a) A velocity is 0. (b) B velocity is equal to A initial velocity, v. (c) I don't know :| (d) Momentum (not sure).
