I understand, sort of...where does the sin 60 come in? Where are you getting "60" from?

The questions is: A wheelbarrow is used to carry a load of 100Kg. The load's centre of mass lies 1/3 of the way between the axis and the point where the handles are held (the distance between the axis and the handles is 1.5m), how much effort will be required to lift the load and hold it at an...

Thank You Did the question again, got resultant force of 243.3 N moving the skier down the slope. Checked my answers...they're right. Thank you. I broke the force of gravity into its parallel and perpendicular parts (to the slope). From the perpendicular component I obtained my normal...

I posted this question once and am still confused as to how to solve, I have spent much time going at it from different directions...It can't be as hard as I am making it out to be. The question is: "A 60kg skier is in a tuck and moving straight down a 30 degree slope. Air resistance pushes...

In Addition... I was also told to try and redo this problem by making my hill or slope be the x axis...I guess draw a tilted axis diagram to make the forces opposing the skier one value...but that confused me a little.

Please Help ASAP: Downhill Skier Question Here is the question: "A 60kg skier is in a tuck and moving straight down a 30 degree slope. Air resistance pushes backward on the skier with a force of 10 Newtons. The coefficient of dynamic friction between the skis and the snow is 0.08. What is...
