The figure below shows an object of mass M = 1,276 g. It is free to move along a horizontal, frictionless surface. This object is further connected to a second object with a mass of m = 1,362 g by means of a massless string that extends around a massless, frictionless pulley. Find the tension of the massless string.

The figure:

M is placed on a table/surface where m is hanging down with the string attaching it to M.

Thank you.

so m is pulling M.

force equation:\

mg=(M+m)a solve for a.

Then, tension = force pulling M or M*a

from the FBDs wouldnt u get

for M:

Fy = N-WM=Ma

Fx=T=Ma

for m:

Fy= T-Wm=ma

Fx= T-W=ma

then solve for a in M of Fx

and sub a into m of Fx to get T?
