As an example, we will apply this procedure to find the acceleration of a block of mass me that is pulled up a frictionless plane inclined at angle with respect to the horizontal by a massless string that passes over a massless, frictionless pulley to a block of mass my that is hanging vertically.

Find a relationship between the x component of the acceleration of block 2, 42x, and the acceleration of block 1. Pay careful attention to signs. Express a2x in terms of ax and/or ay, the components of the acceleration vector of block 1. ▸ View Available Hint(s) 02 = Submit 195] ΑΣΦΑ Part H Complete previous part(s) Provide Feedback → C ?

O řr and Fa and Ě, Submit Request Answer Usually the best advice is to choose a coordinate system so that the acceleration of the system is directly along one of the coordinate axes. If the system isn't accelerating, then you are better off choosing the coordinate system with the most vectors along the coordinate axes. But now you are gaing to ignore that advice.…

A marble is rolling on a table at a constant speed. At the same moment that it rolls off the edge of the table, a penny just drops off the edge. What will happen to them as they fall to the floor?   Part A Both will land at the same time. The marble will land first because it is heavier. The marble will land first because of its greater speed. The penny will land first because it is lighter.

C Example 10 Three boxes are hung from a pulley system as shown in the following diagram. If box A has a mass of 25 kg, box B has a mass of 40 kg, and box C has a mass of 35 kg, what is the acceleration of the boxes? (cord can't be stretched, frictionless pulley. Both cord and pulley have negligible mass) B C
