Question

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.

Answer 1

so m is pulling M.

force equation:\

mg=(M+m)a solve for a.
Then, tension = force pulling M or M*a

Answer 2

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?

Answer 3

Sorry i see the mistake I made

for m the acceleration would be negative since its moving down
