    Conservation of Energy in Elastic Collisions: Solving for Initial Velocity

    So is 4.11 a wrong answer, as well? Sorry, I'm kind of a n00b, I'm just in 1081 and my professor is straight from China and has an extrememly heavy accent so I have no clue what he says when I talk to him. What you guys are saying, though, is that I would have to solve the both the y and x...

    Conservation of Energy in Elastic Collisions: Solving for Initial Velocity

    Hello all, On our test today the question said, "An 2 Kg object is moving along the x-axis and explodes, with particle 1, 1 Kg, shooting north at 3 m/s, and particle 2, 1 Kg, traveling 30 degrees north of east at 5 m/s. What was the initial velocity of the object?" Now I was talking with...
