Дано:             СИ:                   Решение:

V=0,05м.\с.                             F=P=mg

N=1,5кВт         15000Вт            N=Fv=mgv

Найти:                                     m=   N 

m-?                                               g*v

                                                m=1500Вт          

                                                  10н\кг*0,05м\с

                                               m=3000кг.=3 т.
