If this were a theoretical frictionless plane, what would be the mechanical advantage? H + 9H = 10H H ÷ 9H = 1 ÷ 9 9H ÷ H = 9

mechanical advantage (MA = slope/height) here length of slope = 9H height = H 9H so mechanical advantage = ---- = 9 H

OpenStudy (anonymous):

so would it be the first ,second or third

OpenStudy (anonymous):

it will be the third one... 9H ÷ H = 9
