    Work/Energy equation on inclined plane

    Because I'm stupid and it was late! Yeah I should have been more clear but I actually wasnt sure about the grades either(obviously) but you guys cleared both up. You have no idea how much I got stuck on this question, I've never had to ask for help on a physics question before I just couldn't...

    Work/Energy equation on inclined plane

    Billy joule sorted it for me, thanks guys, I've been struggling on this one for a long time.

    Work/Energy equation on inclined plane

    My issue wasnt so much that but I don't know how to work out the resistance without the velocity, and I can't find the velocity without the resistance, and I am unsure how to deal with the energy situation without one of those in this situation. I've been over this same question now so many...

    Work/Energy equation on inclined plane

    h=1 s=30 (h=1*4) /(s=30*4) = 4/120 = height of 4m y4/x120 = 0.03 inv Tan(0.03) 1.7 degrees?

    Work/Energy equation on inclined plane

    I've been trying to work out what I'm doing wrong on this question but I just don't get it. 'A cyclist starting from rest freewheels for 120m down a slope of 1 in 30. At the bottom of the slope the road becomes horizontal, and the cyclist stops without using his breaks after going a further...

    MHB Mechanics work-energy question

    A cyclist starting from rest freewheels for 120m down a slope of 1 in 30. At the bottom of the slope the road becomes horizontal, and the cyclist stops without using his brakes after going a further 40m. If the total mass of the bicycle and rider is 72kg, find the resisting force, assuming it to...
