This was the final bonus question on my first university and I made a serious attempt at it. I know this isn't technically a homework question, so I will understand if it goes unanswered, by founding out if I did this correctly would go a long way to alleviating some of my final exam anxieties...
A 6.0kg box is on a frictionless 35° slope and is connected via a massless string over a massless, frictionless pulley to a hanging 2.0kg weight. What is the tension in the string if the 6.0kg box is held in place, so that it cannot move?
m1= 6.0kg
m2= 2.0kg
θ=35°
So, for Box 1 to be...
