Respuesta :

The power of machine in watts : 400

Further explanation

Given

W=work = 20,000 J

t = time = 50 s

Required

Power

Solution

For mechanical power equation :

[tex]\tt \larged{\boxed{\bold{P=\dfrac{W}{t}}}}[/tex]

P = Joule/s = watt

Input the value :

P = 20000 Joule : 50 s

P = 400 watt
