Hi! First Time Poster.
Thank you for helping me with my problem!
A 28.3-kg block (m1) is on a horizontal surface, connected to a 5.5-kg block (m2) by a massless string as shown in the Figure. The pulley is massless and frictionless. A force of 208.9 N acts on m1 at an angle of 29.7o. The coefficient of kinetic friction between m1 and the surface is 0.201. Determine the upward acceleration of m2.

M2
I'm not sure how to post pictures within my message just yet.
X and Y components of the force on F1
Sum F = M * A
Kf = uK * Fn
g = 9.8m/s
**Y+ is upwards and X+ is to the right**
I found the X and Y components of the Force on M1
I added M1 and M2... not sure if I need this but just in case.
And I drew Free Body Diagrams for both M1 and M2
- M1 has Normal Force acting Y+, which equals its Weight (m*g)... M1 also has Friction and Tension acting X+... the x component of the force acting X-
- M2 only has Tension acting Y+, and Weight (mg)... I suspect the tension to be equal to the tension... but I'm not sure.
Thanks! I hope I gave you enough information!
