a crane does 9,500 J of work to lift a crate straight up using a force of 125 N. how high does the crane lift the crate?
Lina20 [59]

Answer:

<em>The crane lifts the crate up to 76 m high</em>

Explanation:

<u>Work Done by a Force</u>

The work done by a force of magnitude F that displaces an object by a distance y is given by

W=F.y

We know a crane does a work of 9,500 Joule to lift a crate and is using a force of 125 Nw.

The above equation can be solved to know the value of y in terms of the work and the force:

\displaystyle y=\frac{W}{F}

Plugging in the given values

\displaystyle y=\frac{9,500}{125}

y=76\ m

The crane lifts the crate up to 76 m high

This problem must be solved using a sketch. I attached an illustration of the problem.
You must trace the ray that reflects from the top off the table to your eyes. This how eyesight works, light rays reflects off the objects into your eyes.
Law of reflection tells us that light ray reflects off the surface at the same angle in which it falls on it( i attached another illustration of this).
Now we can write tangens equations:
tan(\theta)=\frac{h-0.8}{1}\\&#10;tan(\theta)=\frac{1.8-h}{2.8}\\&#10;\frac{h-0.8}{1}=\frac{1.8-h}{2.8}
We solve for h:
\frac{h-0.8}{1}=\frac{1.8-h}{2.8}\\&#10;2.8h-0.8\cdot 2.8=1.8-h\\&#10;3.8h=1.8+2.24\\&#10;h=\frac{4.04}{3.8}\\&#10;h=1.06m
