what is the quantity of work done when a crane lifts a 100 - n block from 2 m above the ground to 6 m above the ground?\n100 j\n200 j\n400 j\n600 j
Answer
Answer:
C. 400 J
Explanation:
Step1: Determine height change
$\Delta h=6 - 2=4$ m
Step2: Use work - formula
$W = F\times\Delta h$, where $F = 100$ N and $\Delta h=4$ m. So $W=100\times4 = 400$ J.
