Power output is calculated by dividing the work done by the time taken to do that work. In this case, work done is equal to force multiplied by distance, which is mass multiplied by acceleration due to gravity multiplied by distance. Given that the person takes 5 seconds to move 10 meters, we can calculate the speed at which they are moving. Once we have the speed, we can determine the power output using the formula for power, which is work done divided by time.
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)

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
Bike power meters measure the power output of a cyclist by using strain gauges to detect the force applied to the pedals or crank arms. This data is then combined with the speed of the cyclist to calculate power output in 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.
To calculate power, divide the work done (10 joules) by the time taken (20 seconds). This gives a power output of 0.5 watts.
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).
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.
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.
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 ?
Cycling power meters measure the power output of a cyclist by analyzing the force applied to the pedals. They can improve performance by providing accurate data on power output, allowing cyclists to track progress, set goals, and optimize training to increase efficiency and endurance on the bike.
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.
