please helpp i will give like please provide steps too $1.$ Block M$1$ on a horizontal frictionless table is connected to block M$2$ withg a massless string through a hole in the table$($see figure$).$ The part of the string attached to M$1$ is parrallel to the turntable. The blocks have masses M$1=1\mathrm{.}1$kg and M$2=3\mathrm{.}5$ kg$.$ M$1$ is moving in a circle of radius R$=0\mathrm{.}31$ m$.$ Part$($a$)$ What should be the speed of M$1$ so that M$2$ stays stationary in m$/$s$?$ v$=?$ m$/$s Part$($b$)$ How long, in seconds, does it take for M$1$ to make one revolution? t$=?$ s
