I've really really tried to figure this out!What power must a crane generate to lift a tonne of bricks at a speed of 1m/s.It hasn't given a starting height or a time interval, so im a bit lost!
well gravity is the same at the kind on altitudes we go at so unless it is a galactic crane the starting height is irrelevant, the time interval is also useless at you only need to find out basically: how much energy it takes the crane to lift a tonne of bricks one meter in a secondhope this helps!
Tell him to get an electric blanket and a personal heater.
