I have a question on a pulley problem; the problem looks like this:(adsbygoogle = window.adsbygoogle || []).push({});

M (10) ..........O

------------|...

xxxxxxxxxxxx|...

xxxxxxxxxxxx|m (2.5)

xxxxxxxxxxxx|...

With the: O being a frictionless pulley

- being solid ground

. Being a rope

M a mass of 10 kg

m a mass of 2.5 kg

I need to find the tension in the rope.

I have found the acceleration of the masses by:

FM=ma

=10*0

=0 N

Fm=2.5 *9.81

Fm= 24.525 N

A=F/M

A=(24.525 N)/ (10+2.5)

A= 1.962 m/s^2

I know I need to use the equation T= m(g+a) or T=m(g-a) but, I am not sure which one or what mass I am supposed to use. (maybe 2.5 kg?)
