A block of mass m1=3.70kg on a frictionless plane inclined at angle

A block of mass m1 = 3.70 kg on a frictionless plane inclined at angle θ = 30.0° is connected by a cord over a massless, frictionless pulley to a second block of mass m2 = 2.30 kg hanging vertically (see the figure). (a) What is the acceleration of the hanging block (choose the positive direction down)? (b) What is the tension in the cord?

Omg, THANK YOU. This was so much better than just seeing a picture of someone's answer. I am struggling and this helped.

Thank you so much!!!! Was having so much trouble understanding it using my professor’s method. This was so much more visual and easy.

what would the minimum force needed to accelerate the first block up the plane? could you explain

How do you know automatically that both tensions (T1 and T2) are equal?

Where's the video of number 51 problem? The question about figure 5-47? Do you have a solution for that problem?

How can you assume that the smaller block accelerates in the negative direction?

So honestly, spending half of the video explaining what is a triangle and what are sine and cosine is a bit bad

Vid over complicates it, go somewhere else for better info.
