While moving a 71 kg box across a horizontal floor, you find that it takes a 190 n force to get the box moving (pushing horizontally), but just a 120 n force to keep it moving at constant speed thereafter. what is the coefficient of static friction between box and floor? what is the coefficient of kinetic friction between box and floor?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
