An object is positioned at the origin of a set of axes. Two forces act upon it. The first has magnitude 9 N and acts in the direction of the positive y axis. The second has magnitude 4 N and acts in the direction of the negative x axis. Calculate the magnitude and direction of the resultant force.

An object moves in the xy plane with a velocity of 15m s^-1
a direction at 48° above the positive x axis. Resolve this velocity into two components, one along the x axis and one along the y axis.
