Thank you for welcoming me.
Yes it is.
Alright, I know formula for potential energy.
Motor power remains the same. 120 W.
Question is how much time is needed to reach the speed of 0.5 m/s by lifting mass of 20 kg with motor 120 W taking in count potential energy. I hope you can understand...
Okay, here is a question I just can't solve.
The 120W motor starts to lift a load of 20 kg. During which time, this load will reach a speed of 0.5 m / s, taking into account the potential energy.
PS: Ignore losses in the mechanism!
