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!
