If an object starts with an initial velocity of 0, and has a velocity of 1.07 m/s after 20 cm, what is the velocity at 1 meter, assuming a constant acceleration? I do not know how long it takes to travel the full 1 meter. All I know is that after 20 cm the velocity was 1.07 m/s and it took 177...
Thank you for the answer, but I am not a physics person so don't really understand the answer. So in my question, with a metal sphere that is 1.006 kg dropped from 2.5 meters, what is the potential energy, kinetic energy, and mechanical energy? I need to know this value because I need to know...
If a metal sphere that weights 1.006 kg is dropped from 2.5 meters, what is it's kinetic energy when it hits the ground?
Is this kinetic energy the same value as mechanical energy?
If this kinetic energy was converted in electrical energy by a 1000 watt electric generator that was 95%...
Thanks for your reply. The metal spheres drop and pass through a turbine, which is connected to a generator, similar to hydro, or even wind. The specs say it only needs 250 rpm and the output that this particular generator is 3500 W, so I am trying to get it to teh 250 rpm using metal spheres...
Thanks! Your answer shows that the energy from the dropped sphere is 2.45 NM. The generator requires a starting torque of 2 NM, so it looks to me that it would be enough to start the generator. The generator needs to get to 150 NM to get to the rated output of 3500 Watts. Wouldn't dropping a...
I need to do some calculations to know if a metal sphere (iron, steel, whatever) that is 0.25kg is dropped from 2 meters, will it produce enough torque (kenetic energy?) to start a generator with the specifications below? Furthermore, if a metal sphere was dropped every second, continuously...
