Question

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?
0.013 m
76 m
9,400 m
1,200,000 m

Explanation:

Step1: Recall work - force - distance formula

The formula for work is $W = F\times d$, where $W$ is work, $F$ is force, and $d$ is distance.

Step2: Rearrange formula to solve for distance

We need to find $d$, so we can rewrite the formula as $d=\frac{W}{F}$.

Step3: Substitute given values

Given $W = 9500\ J$ and $F = 125\ N$, then $d=\frac{9500}{125}=76\ m$.

Answer:

B. 76 m
