So then it's mgcos(15)?

The tension is along the string, but I was referring to the free body diagram and the fact that the tension is mgsin(60). Is that right?

What I meant to say was... I know that the NORMAL force is mgcos(15). I believe that is right because I drew out the components. I am just sure if it is cos(15) or sin(15)?

I don't understand what you are asking me to do.

I know that the force of the push is equal to 180sin(15) but I don't understand how to incorporate the force of friction.

I don't really understand what you mean.

Alright I drew the free body diagram. I believe that the net force is the up force, the weight is the down force, the force of friction is to the leff of the box, and the force of the push is to the right of the box. The force of friction and force of the push are both at an angle though. Does...

I think there is a tension that is 60 degrees to the left of the down force of mg. Is that righ?

I'm not really sure what the free body diagram would look like.

I'm not sure if I have the right free body diagram. I figured there was a down force of gravity, an up force of net force, and then I don't know what other forces there are.

Honestly, I really don't know how to start this problem. Any help would b great.

Honestly, I don't even know how to start the problem. I really don't know what to do lol.

I really need some help with this problem. PLEASE HELP! Here it is: You are pushing a box uphill the hill has a pitch of 15 degrees above the horizontal, and the static and kinetic friction coefficients between the box and the hill are 0.45 and 0.35. The box has a mass of 40 kg. You push...

I have a homework problem that I've tried to figure out, but I can't figure it out. Here it is: You whirl a ball of mass 0.40 kg on a string of length 0.90 m. At the point shown the angle of the string from the vertical is 30 degrees and the ball has a speed of 3.5 m/s. a) Make a free...
