Approximately 0.01341 horsepower or 0.01 kilowatts.
7.5 watts
Power = Work / time= 600 J / 150 secPower = 4 J/s or 4 Watts (1 Watt = 1 J/s)
100
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts

Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
10 joules of work in 1 second
7.5 watts
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
100 watts
1800 joules / 1 minute = 1,800 joules / 60 seconds = 30 joules per second = 30 watts.
Power (Watts) is Joules (energy) per Second (time) so divide the number of joules by the number of seconds. 104/60 = 1.733 Watts
A power output of 25W for one second is 25 joules. It is also 0.03 horsepower (electric motor scale)
The power rating of the bulb indicates how much power it uses. The power in watts indicates how much energy in Joules the bulb uses in one second. A bulb should have its voltage and power printed on it.
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
Power is energy per unit time. So, the required power is 900/90 = 10 Watts.
