Using vectors to determine the horizontal acceleration when force is applied at an angle.
Solving Problems with Forces at Angles
In this problem a box is slid across the floor. You are asked to calculate the friction coefficient between the box and the surface of the floor. The tricky part is that the force is applied at an angle (not directly horizontal). This take you through the steps.
An example of using trigonometry to break up a force vector into its x (horizontal) and y (vertical) components.
Resolving a force is about replacing a force by two forces at right angle to one another that would have the same effect as the single force. The forces that replace the single force are called the components of the force.
