Answer: 4.27 x 10^-10 N to the left
Explanation: I just took this quiz
You move a 25 N object 5.0 meters. How much energy did you transformed?
25n x 5m = 125 J
Her <span>acceleration is 8.75 hope is helps</span>
<h2>Potential energy lost by 10 N rock will be greater</h2>
Explanation:
Two rocks of 5N and 10N falls from the same height . Thus they will loose the potential energy.
The potential energy lost = mass x acceleration due to gravity x height
The potential energy lost by first 5 N rock = 5 h
Because weight of rock m g = 5 N
Similarly , the potential energy lost by 10 N Rock = 10 h
here weight of rock m g = 10 N
Thus comparing these two , the potential energy lost by 10 N rock is greater than that of 5 N rock .
