A block of mass m1 = 3.70 kg on a frictionless inclined plane of angle 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2= 2.30 kg hanging vertically. What are (a) the magnitude of the acceleration of each block and (b) the direction of the acceleration of m2? (c) What is the tension in the cord?
The Attempt at a Solution
I set the coordinate system according to the diagram above.
Then I plug in both of them.
Then I sub in the values
I don't know what I did wrong. The correct answer is 0.735.
