Homework Equations

F = ma

The Attempt at a Solution

So , i drew a freebody diagram for the 6k gram block, and the tension to the right of I call T2.
Therefore, the force of gravity component parallel to T2 is (6*9.8)sin30. Therefore, T2 is equal to this value which i found is 29.4! However, i don't think this is right!

You think correctly: you forget about the acceleration...

You think correctly: you forget about the acceleration...

what do you mean? :(

I see... i got the answer 41. I had to set netforce for each of them to ma

 

[Dr.D]

He is saying that you neglected to include the acceleration.

i realized that i should be take the sum of the forces on each object and setting it equal to the Fnet. I only realize this till now! Few more hours until the exam :(!

In these questions first try to make free body diagram clearly and then write equation accordingly.
