What is the magnitude and direction of the resultant force of 3N horizontal and 5N vertical?
Magnitude:
Find the square root of 3^2+5^2=root of 34=5.83N (3sf)
Direction:
Draw a triangle with 3N at the bottom, 5N going up and the hypotenuse then represents the resultant force.The direction will be the angle between the horizontal and the hypotenuse.We know the adjacent (3N) and the opposite (5N) so we use tan.tan^-1 (5/3) =59.0 degrees (3sf)
