Physical science
A box a weight of 100 N rests on a horizontal floor.The coefficient of static friction is 0,40 and the coefficient of kinetic friction is 0,30.DETERMISE THE FRICTIONAL FORCE ACTING ON THE BOX IF A HORIZONTAL FORCE IS APPLIED WITH A MAGNITUDE OF 0 N

A tractor pulls a tree trunk across a horizontal piece of ground.If the force in the chain is 3000N and the chain forms an agle of 30 degrees with the ground,calculate:The forces with which the tree is pulled across the ground.

a book,initially at rest is pushed along a horizontal table top by a horizontal force of 2N. After 1s it has been moved 1.5m. The force of friction is 0.4N much work is done on the book by the 2N force? much work is done on the book by friction? c.what is the books...
