Question

The same person walking takes a longer stride. He still exerts a downward and forward force of 180 pounds but now at an angle of -45 degrees (315 degrees) to the ground. Resolve the forces into their perpendicular (vertical) and parallel (horizontal) components and label each component also calculate the magnitude of the component forces using trigonometric functions. Show ALL of your work use appropriate symbols.

Answer 1

Here the force can be resolved as in the diagram shown below F cos θ Fsin θ Horizontal component of force F 800.68N Fr800.68x cos(-45) 566.16N

Vertical component of FFsin F 800.68N force F, -800.68x sin(-45) -566.16N
