1. A man is pulling on his dog with a force of 70.0 N directed at an angle of +30.0 to the horizontal. Find the x- and y-components of this force. 2. A gust of wind blows an apple from a tree. As the apple falls, the gravitational force on the apple is 2.25 N downward, and the force of the wind on the apple is 1.05 N to the right. Find the magnitude and direction of the net force on the apple. 3. Two tugboats pull a barge across the harbor. One boat exerts a force of 7.5 x 10* N north, while the second boat exerts a force of 9.5 x 10* N at 15.0 north of west. Precisely, in what direction does the barge move
