Power = (energy) / (time) =
(35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
1200j
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied. In this case it would be 300N x 10m to get 3000J. This energy is transferred in 10 seconds and since power is energy transferred per unit time... 3000J divided by 10 seconds equals 300 Watts or 300 Joules per second.
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
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.
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.

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 the weight of the mass, you can use the formula: Power = Force x Velocity. Given the power (726 watts) and distance (36 meters), you can find the force. Then, divide the force by acceleration due to gravity (9.8 m/s^2) to find the weight in Newtons.
The work required to move the truck is 600 N (600 kg-m/sec2) times 30 meters = 18000 joules. If this is done in 15 seconds, the average power was 1200 watts (kg-m2/sec3).
two watts a second
Power (the rate of energy use) is calculated as the product of the energy exerted (work) divided by the time over which the energy is released. P = W/t To solve the example, multiply the force in Newtons by the displacement in meters to find the work in joules, then divide by the time to find the power required, in watts (joules/second, or kg-m2/sec3) 100 N x 10m = 1000 joules divided by 10 seconds = 100 watts
Power is the rate at which work is done. Using the formula for power (Power = Work / Time), we can calculate it by first finding the work done, which is force multiplied by distance (Work = Force x Distance). Work = 200 N x 8 m = 1600 Joules Power = 1600 J / 2 s = 800 Watts
A force of 100 newtons acting through a distance of 10 metersresults in 1,000 joules of energy transferred.If it all takes place in 10 seconds then the average rate of energytransfer (power) during that interval is(1,000/10) = 100 joules per second = 100 watts.
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied. In this case it would be 300N x 10m to get 3000J. This energy is transferred in 10 seconds and since power is energy transferred per unit time... 3000J divided by 10 seconds equals 300 Watts or 300 Joules per second.
The direction of the force is to the right. To calculate the magnitude of the force, you can use the formula: Force = (mass x distance) / time. Here, the force is 10 Newtons, the distance is 4 meters, and the time is 9 seconds. Plugging these values into the formula, the magnitude of the force is about 4.44 Newtons.
Power is calculated as work done divided by time taken. The work done is force multiplied by distance, which in this case is 200 N * 10 m = 2000 J. Plugging in the values, the power required would be 250 Watts.
