When your velocity is changing, your net force ___ equal to 0.0N.

20Kilowatt

Explanation:

Power is the rate of work done per time. It can be calculated using the formula:

Power = Energy/time

Energy = mass × acceleration due to gravity × height ÷ time

Power = mgh/t

Where;

m = mass (1000kg)

g = acceleration due to gravity (10m/s²)

h = height (10m)

t = time (s)

Power = 1000 × 10 × 10 ÷ 5

Power = 20000 watt

In kilowatt = 1000watt, the power is:

20Kilowatt or 20Kw
