Mass m1 on the frictionless table of the figure is connected by a string through a hole in the table to a hanging mass m2. (Figure 1) With what speed must m1 rotate in a circle of radius r if m2 is to remain hanging at rest?
Added by Donald R.
Step 1
First, we need to understand that the tension in the string is providing the necessary centripetal force to keep m1 moving in a circle. Show more…

Mass $m_{1}$ on the frictionless table of FIGURE P8.46 is connected by a string through a hole in the table to a hanging mass $m_{2},$ With what speed must $m_{1}$ rotate in a circle of radius $r$ if $m_{2}$ is to remain hanging at rest? (FIGURE CAN'T COPY)
A disk of mass $m$ on a frictionless table is attached to a hanging cylinder of mass $M$ by a cord through a hole in the table (see Fig. 5-42). Find the speed with which the disk must move in a circle of radius $r$ for the cylinder to stay at rest.
A mass $m_{1}$ undergoes circular motion of radius $R$ on a horizontal frictionless table, connected by a massless string through a hole in the table to a second mass $m_{2}$ (Fig. 5.33). If $m_{2}$ is stationary, find expressions for (a) the string tension and (b) the period of the circular motion.
