- Homework Statement
- Suppose that the cart (mass m) oscillates so that the maximum speed attained is v. The amplitude of the cart’s motion is A and the force constant of the spring is k. Suddenly, an axle supporting the wheels breaks so that one of the wheels can no longer rotate and is locked in its position. This would cause the cart to begin to experience friction. In terms of m, v, A and k, write an expression for the maximum amount of work that the force of friction can perform on the cart after the axle breaks.
- Relevant Equations
- work, kinetic energy, potential energy
I took a stab at the question, but I don't think I did it right.
I know that Work = Change in Energy
thus, Work = final energy - initial energy
Because there is no energy at the final position, then final energy = 0 (I'm not sure if this is correct).
So I got the equation W = 0 - (1/2kA^2 + 1/2mv^2)
Is this correct at all?
