Thanks for the reply, Matterwave. I understand what you are saying. It's hard for me to look at a straight line (like in the case of FG at 270°) and apply trigonometric values. I can see that if we correlate sinθ with the y-axis, and cosθ with the x-axis, that FG at 270° = mgsinθ where...

All degrees are measured from the positive x-axis. FG = Force of gravity FN = Normal force FT = Force of tension Problem: A skier is being pulled up a 15° incline by a rope. I'm solving for FT. The only forces acting on the skier are FG, FN, and FT. Attempt at a solution: Initially, my...

Thanks for the reply, ehild. I initially responded with another question, but I think I understand now.

Homework Statement [/B] A 0.20-kg block and a 0.25-kg block are connected to each other by a string draped over a pulley that is a solid disc of inertia 0.50 kg and radius 0.10 m. When released, the 0.25-kg block is 0.30 m off the ground. What speed does this block have when it hits the ground...

Homework Statement Edward and Jacob, standing face-to-face on a horizontal sheet of frictionless ice, push off each other, causing each to slide backward. Jacob is more massive than Edward. After the push, which of the two is moving faster? Homework Equations Conservation of momentum: Pi = Pf...
