It takes the person 5 seconds to move 10 meters What is the power output?
The person's speed is 2 meters per second. The power required for him to accomplish that depends on his weight, on his efficiency of movement, on whether he's moving horizontally or vertically, etc., all of which the question neglects to specify.
What is the power if 35N force 5 Meters and takes 19 seconds to push?
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
How many ms are in 6.7 seconds?
6.7 times 10 to the -3 power
During a winter storm an entire town lost power for 2.6 hours How many seconds is this?
2.6 hours = 2.6*60 minutes = 156 minutes = 156*60 seconds = 9360 seconds.
How much power is needed to do 1200 Joules of work in 90 seconds?
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.
A weightlifter expends 294 W of power lifting a weight to a height of 2 m in 10 seconds What mass has he lifted?
assume a = 10(m/s)/s power (w) = energy change/time 294 = (mass * 10 * 2)/10 then mass = (294*10 )/ (10*2) = 147kg
What is the power expended when a barbell is lifted 2.2m in 2 seconds?
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.

A power mower does 9.00 times 105 J of work in 0.0500h. what power does it develop?
You need to convert the time to seconds. Then, if you divide the work (in joules) by the time (in seconds), you will get the power in watts.
