Awarehouse worker pushes a crate along the floor. the worker pushes with a force of 10 n that points downward at an angle of 45° below the horizontal. what component of the force moves the crate forward?
7.8 n
3.4 n
7.1 n
10 n

The component of the force that moves the crate forward is equal to 7.1N(third option).

Why?

Since the force is applied at an angle (45°), the force has two components (horizontal and vertical). We can calculate the component that pushes the crate forward by the following way:

Have a nice day!

falling water hydro = water .. spectcular places these plants are

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
