Answer:

7.5Watts

Explanation:

Given parameters:

Force of lift  = 25N

Height  = 3.6m

Time  = 12s

Unknown:

Power output  = ?

Solution:

Power is the rate at which work is done ;

     Power  = [tex]\frac{force x height }{time}[/tex]  

   Power  = [tex]\frac{25 x 3.6}{12}[/tex]    = 7.5Watts
