Thanks Nasu. To answer zapper z, i arrived at the power via the following steps: - velocity: v = √2gh = √2x9.8x100 = 44.27 - Kinetic energy: KE = 1/2mv² = 1/2 x 1000 x 44.27² = 980000J - Power (w): P = E/t = w = J/s w = 980000 / 2.25 = 435555.5w (435.5KW) Are my calculations correct...

Thanks for the replies. Catching the object and slowing it down would apply if if the object would hit the turbine as in the hydro-electric system. But what if the object is connect to a rope which in turn spins the turbine as the object drops - hence the relevance of the time. Jtbell, would...

Hi guys, I have a question that has been intriguing me for some time. If i drop an object 100m at the speed of gravity (9.8), which has a mass of 1000kg - given the initial velocity of zero, i get the following results: velocity = 44.3 m/s Kinetic energy = 980000 Joules If my...
