A block sits on a slope that has an angle of 10. to the horizontal. There is a coefficient of static friction us = 0.3 between the block and the slope. You apply a force to the block in an attempt to pull it up the hill. Calculate the angle to the horizontal at which you should apply this force to maximise your chances of being able to make the block move up the hill.

Answer rating: 100% (QA)

frictional force acting on the block opposes the motion uphill so to maximize the chance of moving the block up the slope we need to apply a force tha... View the full answer
