w JAKIM CZASIE SILNIK DZWIGU O mocy 6kw podniesie płytę 6000N na wysokosc 10 m?

P = 6kW = 6000W F = 6000N h = 10m t = ?                                        P = W/t                                        W = F * h                                                                            P = (F*h)/t     | *t                                     P*t = F*h        | :P                                       t = (F*h)/P                                     t = (6000N*10m)/6000W                                     t = 10s
