How much power is required to carry a 35 N package a vertical distance of 18 m if the work on the package is accomplished in 30 s?

P = 21 watts

Explanation:

Given that,

Weight of a package, F = 35 N

Distance, d = 18 m

Time, t = 30 s

We need to find the power required to carry the package. Power is equal to the work done divided by time. So,

So, the required power is 21 watts.

the answer is neither ball has a charge.
