If your weight is 140 pounds what size force do you feel pushing back on your feet as you stand on the floor?
This involves Newton's third law of motion; for every force there is an equal and opposite force. If your weight is 140 lbs, then you're exerting 140lbs of force on the floor. In response, the floor is exerting 140lbs of force on you.
A 40N force pulls a 4kg block a horizontal distance of 8m The rope makes an angle of 35 degrees with the floor and the kinetic friction is equal to 0.2 What is the work done?
The horizontal component of 40N at 35° is 40 cos(35°) = 32.7661 N (rounded)The friction is irrelevant, and so is the mass of the block. I'm not sure that all thegiven numbers even add up ... a 4Kg block sitting on a friction coefficient of 0.2might not need 32.7661 N to slide it along the floor, or it might need more than that.We don't care. All we need in order to calculate the work is the force and the distance.Force = 32.7661 NDistance = 8 mWork = (force) x (distance) = 262.1287 Joules(rounded)The vertical component of the 40N just goes along for the ride, and it doesn't doany work. We know that because the front of the block doesn't lift up off the floor,so the vertical component doesn't move through any vertical distance.
How much energy is required to raise a mass of 200kg to a height of 4 m?
Potential energy of the mass referred to the floor level = M g H .At 4 m above the floor, its potential energy will be M g H = (200) (9.8) (4) = 7,840 joules.That's the energy you have to come up with from somewhere in order to hoist the block.
