Question

a rock climber carrying a backpack has a total weight of 600 n. how much work is done when she climbs 12 m in 10 sec?
a 50 j
b 60 j
c 720 j
d 7200 j

Explanation:

Step1: Recall work done formula

Work done $W = F \times d$, where $F$ is force (equal to weight here) and $d$ is vertical distance.

Step2: Substitute given values

$F = 600\ \text{N}$, $d = 12\ \text{m}$
$W = 600 \times 12$

Step3: Calculate the result

$W = 7200\ \text{J}$

Answer:

D 7200 J
