5 0

Answer:

  C.  98 J

Explanation:

The appropriate formula is ...

  PE = mgh . . . . . m is mass; below, m is meters

  PE = (5 kg)(9.8 m/s^2)(2 m) = 98 kg·m^2/s^2

  PE = 98 J

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
