Hello Mate!
Question:
The power of a crane is 25000 watt. Calculate the time required by it to lift a load of 6000 kg up to the height of 20 metres.
Solution:
We have,
Power [P] = 25000 Watt
Mass [m] = 6000 kg
Height [h] = 20 metres
Time [t] = ?
Now,
P = W/t = F × d/t = m × g × h/t
Or, 25000 = 6000 × 10 × 20/25000 [.......g = 10 m/s^2]
Or, t = 6000 × 10 × 20/25000
Or, t = 1200/25
Therefore, t = 48 second
Hence, the required time for the crane to lift the load is 48 seconds.
Hope It Helps!
