    Trying to find Velocity and Kinetic Energy

    It would be the left hand side that is conserved which would make: (1/2)m_1(V^2) = (1/2)m_2(V^2) + W_nc But what would I do after that if that is the correct equation? -Rhaen-

    Trying to find Velocity and Kinetic Energy

    The problem is as follows: A 4.0 kg mess kit sliding on a frictionless surface explodes into two 2.0 kg parts, one moving at 3.0 m/s, due north, and the other at 5.0 m/s, 30 degrees north of east. (a) What is the original speed of the...

    Maximizing Potential Energy in a Falling Mass-Spring System

    So then the equation qould go: 0 = (1/2)mv^2 + mg(y_1-y_2) + (1/2)ky^2 0 = (.1kg)v^2 + (.2kg)(9.8)(y_1-y_2) + (49)y^2 If that is the case then how would I calculate the y distance so that I can have only the variable for velocity remaining? Thank you for your time. -Rhaen-

    Maximizing Potential Energy in a Falling Mass-Spring System

    Ok so far all I have been thinking I could do with part a is this... (a) (1/2)mv^2 + mg(y_1-y_2) = (1/2)mv^2 + mg(y_1-y_2) This comes from the equation K_1 + U_1 = K_2 + U_2 I don't know if I am missing something in that equation though. I know that there will be cancelations, I think...

    Maximizing Potential Energy in a Falling Mass-Spring System

    Hello all, I am looking for some assistance with a physics problem that I have for my physics class. Any help would be greatly appreciated because I have no idea where to start. Thank you all ahead of time for your help. The problem is: A 10-g mass is attached to the end of an...
