- Homework Statement
- A block of mass m is placed on a plank of mass M that rests on a frictionless floor. The block is connected to an obstruction on the plank with the help of a light spring of stiffness k as shown in the figure . Coefficient of friction between the plank and the block is μ. Initially when the spring is relaxed , the block is given a velocity Vo towards the obstruction . If the block stops on the plank before reversing its direction of motion relative to the plank , find the velocity Vo . Acceleration due to gravity is g.
- Relevant Equations
- Momentum conservation
Work - Energy theorem (?)
I don't understand the question. If it want the mass to stop and reverse its direction, then does that not means ##vo## can be anything? (obviously not 0 since it will make the system not moving at all).
