### Force and Motion-IIApplying Newton’s Second Law to More Complex Problems:The Atwood Machine and the Inclined Plane.

Lecture 5

Thursday:29 January 2004

Motion in Two-Dimensions
• Motion in x direction is completely independent of motion in y direction.
• Break problem into two parts. One regarding x-motion, one regarding y-motion
• Each part is then handled just like motion in 1-Dim.
What do we know?
• Is tension the same for both masses?
• Is acceleration the same for both masses?
• Is the acceleration equal to g?

Problem Solving Tip:Rotate your coordinate system for the inclined plane. Make one axis along the direction of motion.You can leave the coordinate system in the “traditional” form for the hanging weight.

N - m1g cos q = 0 m2g - T = m2a
• - m1g sin q = m1a
• Add the two equations involving T, in order to eliminate T.
