In case it's not obvious, be sure to draw three free body diagrams, one for each object. To be precisely correct, you'd want initially label the tensions in each rope as separate variables.
Webpractice problem 2. A swimmer heads directly across a river swimming at 1.6 m/s relative to still water. She arrives at a point 40 m downstream from the point directly across the river, which is 80 m wide. Determine…. the speed of the current. the magnitude of the swimmer's resultant velocity. Web28 CHAPTER 2. KINEMATICS IN 1-D Displacement as an area If an object moves with constant velocity v, then the displacement ∆x during a time ∆t is ∆x = v∆t. In other words, the displacement is the area of the region (which is just a rectangle) under the v vs. t “curve” in Fig. 2.2. Note that the displacement (which is ∆x by ...
