A suitcase is dragged across a tiled floor with a strap that makes an angle of 40 degrees with floor. what is the component of the force parallel to the floor if a 75N force is exerted?

To find the component of the force parallel to the floor, we need to use trigonometry. Specifically, we will use the cosine of the angle between the force and the direction parallel to the floor.

Given:
- The force \( F = 75 \) N
- The angle \( \theta = 40^\circ \)

The component of the force parallel to the floor \( F_{\parallel} \) can be found using the cosine function:

\[
F_{\parallel} = F \cos(\theta)
\]

Plugging in the values:

\[
F_{\parallel} = 75 \cos(40^\circ)
\]

To compute \( \cos(40^\circ) \), we use a calculator or a table of trigonometric values:

\[
\cos(40^\circ) \approx 0.766
\]

Therefore,

\[
F_{\parallel} = 75 \times 0.766 \approx 57.45 \text{ N}
\]

So, the component of the force parallel to the floor is approximately 57.45 N.
