Two workers are trying to move a heavy crate. One pushes on the crate with a force , which has a magnitude of 485 newtons and is directed due west. The other pushes with a force , which has a magnitude of 310 newtons and is directed due north. (a) What are the magnitude and direction of the resultant force + applied to the crate? (Express the direction relative to due west.) magnitude N direction ° of west (b) Suppose that the second worker applies a force - instead of . What then are the magnitude and direction of the resultant force - applied to the crate? magnitude N direction ° of west please show all work
