heat is transfered causing it to melt
Answer:
<h3>The answer is 9 kg</h3>
Explanation:
To find the mass given the force and acceleration we use the formula

where
f is the force
a is the acceleration
We have
f = 18 N
a = 2 m/s²
We have

We have the final answer as
<h3>9 kg</h3>
Hope this helps you
Understanding the given:
85 kg mountain climber
6.50 m long rope
gravity = 10m/s2
If we want to identify the work done on this scenario
we get f = 85kg x 10m/s2 = 850 N
w = 850N x 6.5 m = 5525 J
