A 40 kg crate is pulled 50 m along a horizontal floor by a constant force exerted by a person, Fp = 150 N, which acts as 30 degree angle. The floor is rough and exerts a friction for Ff = 40 N. Determine: a) the work done by each force acting on the crate b) the net work done on the crate
A mass m = 15 kg is pulled along a horizontal floor with NOfriction for...
A mass m = 15 kg is pulled along a horizontal floor with NO friction for a distance d =7.1 m. Then the mass is pulled up an incline that makes an angle θ = 30° with the horizontal and has a coefficient of kinetic friction μk = 0.38. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 30° (thus on the incline it is parallel...
