Solve Pulley Question Homework: Find Acceleration, Tension & Speed

[student 1]

Homework Statement

Two objects are connected by a light string that passes over frictionless pulley. Draw free body diagram of both objects. Assuming the incline is frictionless, m1= 2.00kg m2= 6.00 kg and the angle is 55. A. find the accelerations of the objects, B. the tension in the string. C. the speed of each object 2.00 seconds after they are released from rest.

The picture is a triangle with M2 sitting on the hypotenuse connected to the pulley and M1 hanging from the pulley. The angle that is 55 is not the one the pulley is on. I hope this helps!

Homework Equations

The Attempt at a Solution

The free body diagrams are confusing me and I have no clue where to go to find the acceleration even if I did have the right diagram drawn.

Apply Newton's 2nd law to both objects and solve for a. Likewise, you can solve for T, as well.

How would you solve for T?

Hi student_1,

If it's the drawing of the free body diagrams that are giving you trouble, could you post a picture of what you got? Or at least describe how you drew them?

If you have the right diagrams, then what equations do you get from them (following konthelion's advice about using Newton's second law). You solve for a and T from those equations.

View attachment untitled.bmp I hope this drawing helps a little bit. Mass of 1=2, Mass 2=6 And the angle is 55.

Look at each mass separately and use Newton's 2nd law to find the acceleration. So determine which forces are acting on each object and then you will be able to solve for acceleration.
