Ahh, okay. Unfortunately during the lab I couldn't use any other masses. Therefore I could not find the mass of the cart.

The first equation is equating and isolating for for F (force of friction). I'm getting m1g=F+m2gcostheta instead of sin. I'm not quite sure how we are using sin instead of cosine.

So in this experiment I will raise or lower the ramp as I need to to keep the two balanced, than adjust it so that the mass pulls it down? The force at which it just starts to move is the static force Mewstatic. I am not sure how to link forces together with energy. If there is a static...

I was told that I cannot use anything but a metre stick. I am also stumped, also the mass is not given for the cart.

1. Determine the percent efficiency of the system www.imageshack.us/photo/my-images/818/photokt.jpg2. Ek=\frac{mv^2}{2} Eg=mgh W=FΔd W=ΔE 3. I am assuming energy is lost in this system due to friction possibly. Also assuming gravity is 9.81m/s^2 The mass of the the suspended object will be...
