Solved
Got it. I think I was over complicating it because I started with the last equation. But it seems easier than I initially thought. Perhaps because I still am a little rusty on trig functions.
So:
Tcos50 -75n =ma = 0 is 75N/cos50 = T = 116.7N
This gives me the force that is...
Thank you for the reply.
I am still a bit confused though. I used the equation that my teacher worked out in class. When I do that equation with the coefficient of static friction that the answer gives, my solution is correct. So I know that it is the right formula, or at least will yield...
Homework Statement
A student pulls her 22-kg suitcase through the airport at constant velocity. The pull strap makes an angle of 50 degrees above the horizontal. (a) If the frictional force between suitcase and floor is 75N, what force is the student exerting? (b)What's the coefficient of...
Solved I think
So right after I posted this, I think I solved it:
The two tension forces cancel out and the normal force on the glider and the weight force for the glider cancel out. So the only force remaining is the weight force on the 100g hanging mass right? So then I do...
Homework Statement
A 230-g air track glider is connected to a string hanging over a frictionless pulley. A 100-g mass hangs from the other end of the string. a) Draw force diagrams for the glider and the hanging mass. b) Find the acceleration of each.

Homework Statement
A 0.075-kg arrow hits the target at 21 m/s and penetrates 3.8cm before stopping. (a) What average force did the target exert on the arrow? (b) What average force did the arrow exert on the target? (c) An identical arrow strikes the target at 42m/s. If the target exerts the...
