A 150 Newton force is pulling 70 degrees above the horizontal and somewhat to the right. Tell me first the vertical and second the horizontal magnitudes in Newtons of the two smaller vectors that could be added to get this larger vector.

To push a crate from point A to point B at the door of a warehouse, a resultant force of 2500 ? is needed. To accomplish this, Pedro Juancho, and Joe Marie volunteered to push the crate. If Pedro exerts 750 ? and Juancho exerts 1500 ? in the direction shown, determine the force that Jose Marie must exert to move the crate to desired location.
