Homework Statement
A block of mass m1 = 6.75 kg on a frictionless plane inclined at angle = 30.3° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.07 kg hanging vertically (Fig. 5-54). (a) What is the acceleration of the hanging block (choose the positive direction up)? (b) What is the tension in the cord?
Homework Equations
Fynet= T-m2g= m2a aka T=m2g+m2a
Fxnet=m1g(sin)-T=m1a
when these two are put together it is, a=(m1g sin - m2g)/(m1+m2)
The Attempt at a Solution
So I used the equations above and first found acceleration to be -1.914m/s squared and then I used the acceleration and plugged it back into the problem to find T and I got it to be 16.32 N, these answers are wrong and I don't know what I did wrong. Can someone help me please?
