A 60.0-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.760 and 0.410, respectively. What horizontal pushing force is required to (a) just start the crate moving and (b) slide the crate across the dock at constant speed? Important: Assume that the pushing force is to the right

Static frictionis the friction that occurs in thebodywhen the body is just about tomove. Thestatic frictionforce will be446.88 N.While thekinetic frictionforce will be241.08 N.What is the friction force?It is a type ofoppositionforceacting on thesurfaceof the body that tries toopposethemotionof the body. its unit isNewton(N).Mathematically it is defined as the product of the coefficient of friction and normal reaction.mis themassof crate = 60 kgμsis the coefficient ofstatic friction = 0.760μk is the coefficient ofkineticfriction= 0.410(a)Static frictionis thefrictionthat occurs in the body when the body is just about tomove.Hencestaticfriction forcewill be 446.8 N.(b) When thebodyis moving in astraightandinclined planethevalueoffriction forceacting on the body is known askineticfriction.Hencekinetic friction forcewill be 241.08 N.To learn more aboutfriction forcerefer to the link;brainly.com/question/1714663...
