Two workers are moving a crate (m=45kg) across ahorizontalfloor. One work is using a rope attached to the crate.Thetension in the rope is 65 N and is directed at 20 degrees abovethehorizontal. The second worker pushes on the crate with ahorizontalforce. The coeffecient of kinetic friction between thecrate andthe floor is 0.17. A) What force must the second worker push with for the cratetomove at a constant velocity? B) The second worker needs to move another identicalcratewithout the help of the other worker. If the coeffecient ofstaticfriction between the floor and crate is 0.32, whatminimumhorizontal force is necessary to get the crate moving?
