∙ 14y agoThe 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.

To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.The power is the rate at which the energy is delivered. It takes more powerto lift the load faster.The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),and the unit of the answer is watts.
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
Work = (800 newtons) x (10 meters) = 8,000 newton-meters = 8,000 joulesPower = (work) / (time) = (8,000) / (5) = 1,600 watts
Frank's power output is 400 watts (W). This is calculated by dividing the work done (2400 J) by the time taken (6 seconds), which results in a power output of 400 W.
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
No, as the time required for a person to do work increases, their power output decreases. Power is defined as the amount of work done per unit of time, so the longer it takes to do work, the lower the power output.
Your power output would be 100 Watts. This can be calculated by dividing the work done (force x distance) by the time taken to do the work (10 seconds).
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
Power is equal to work done divided by time, where work done is force multiplied by distance. In this case, the work done is 100 newtons * 10 meters = 1000 joules. Therefore, the power used would be 1000 joules / 5 seconds = 200 watts.
a machine applies a force of 100 newtons over a distance of 10 meters to raise a500 newtons drum 1.5 meters. what is efficiency of the machine ?
The power output can be calculated as the work done divided by the time taken, so P = W/t. Plugging in the values: P = 200 J / 40 s = 5 watts. Therefore, the power output is 5 watts.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
Multiply 200 MW by the amount of time (in seconds) that the plant runs (86400 seconds in a day). This gives 1.728 * 10^16 Joules in a single day.
Your power output is 800 watts. This can be calculated using the formula: Power = Work/Time = Force * Distance / Time = 200 N * 8 m / 2 s = 800 watts.
