a machine lifts a 50 kg mass to a height of 60 m in 4s. Calculate the power developed by the machine (take g= 10 m/s)​​

Explanation:

Power is given by , where is work and is elapsed time. To calculated work, we'll use , where is force and is displacement. Substituting given values, we have:

.

Now plugging this in to our power equation, we get:

The power developed by the machine is 7700 Watt.

Explanation:

this is a good question! i'll do some research and come back when i have the answer!
