Acceleration on a Frictionless Wedge

Click For Summary
SUMMARY

The discussion focuses on calculating the acceleration of a system involving two masses, m1 and m2, connected over a frictionless wedge. The key equation used is F = mgsinθ, which applies to the forces acting on both masses. The solution involves analyzing the free body diagrams for each mass and recognizing that the frictionless and massless nature of the pulley ensures that both masses accelerate at the same rate. This leads to a definitive expression for the system's acceleration based on the gravitational force components acting on each mass.

Homework Statement



Two masses m1 and m2 (m1 > m2) are connected over a wedge shaped block. Assuming both inclined planes are frictionless along with frictionless and massless pulley, calculate an expression for the acceleration of the system.

Here's what it sort of looks like: http://prntscr.com/df5lh

Homework Equations



F = mgsinθ ( I think )

The Attempt at a Solution



Finding F of both blocks, and minusing one from the other.

Take each block separately and draw the free body diagrams for each, using an appropriate coordinate system. If the pulley is frictionless and mass less, we have a 'no slip' circumstance, which means if m_1 accelerates some distance down the incline, m_2 will accelerate up the other incline at same rate. This will help when equating expressions later on.
