Didn't learn that yet. Do I need to find theta first?

What does this question ask for and what do I have to do to get the answer?
3. ### Find the components for F (AC)?

I am able to find the components for AC but how do I get the components for AB using the angles? Is there a formula for it?
4. ### Find the components for F (AC)?

I have to find the components for F (AC)?
5. ### Find the components for F (AC)?

I don't know how to start off. What steps do I have to take to solve this problem? I am completely lost.
6. ### Tension on string pulling up water

What if the acceleration is downwards? Would it be T = mg - ma? Does anyone know?
7. ### Tension on string pulling up water

Am I supposed to plug in -9.8 since gravity is pulling it down or 9.8 since the negetive is already in the formula for g?
8. ### Tension on string pulling up water

Is it F = T-mg=ma?
9. ### Tension on string pulling up water

A 6-kg of water is being pulled straight up by a string. The upward acceleration of the bucket is constant, with magnitude 3 m/s^2 I need to find Tension. I have a problem getting the formula for this question. Can someone please help me? Thanks!
10. ### Average Velocity

yea sorry. i meant delta x over delta. i still dont no how to do it and its 3 am now! i have to go to sleep. ahhhhh. can someone please help me quick?
11. ### Average Velocity

the thing is it doesnt tell u exactly what the position is at t = 5. it is between 40 - 60 and it said not to eyeball it. i thought it was 45 and i used it in the formula and got 6.3 and got the wrong answer. so what should i do now?
12. ### Average Velocity

delta v over delta t. i dont no the velocity for t = 5.
13. ### Average Velocity

Does anyone know how to do this? Thanks!
