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.
200 newton-meters per second = 200 watts.
Weight of a mass of 50 kg = [ m g ] = (50 x 9.8) = 490 newtons.Work = force x distance = 490 x 4 = 1,960 newton meters = 1,960 joules
1.542 meters.

The work done to lift the sack of potatoes vertically 6.5m can be calculated using the formula: work = force x distance, where force = mass x gravity. So, the work done would be approximately 1274 Joules.
10 METERS
That takes 80 foot-pounds, equivalent to about 59 joules.
The work done to lift a 25kg sack of cement vertically 4.3m is approximately 1075 Joules. This can be calculated using the formula: Work = Force x Distance, where Force = mass x gravity = 25kg x 9.81 m/s^2 and Distance = 4.3m.

I believe it is approximately 1.13 cubic meters (1.13 litres will lift 1 gram; do the math.
The work done by a crane to lift a 1 kg car 10 meters would be 98.1 Joules. This is calculated as the product of the force required to lift the car (9.81 N/kg) and the distance the car is lifted (10 meters).
The work done to lift the petrified log 5 meters can be calculated using the formula: work = force × distance. In this case, the work required would be 25,000 joules (5000 N × 5 meters).

The work done to lift the log can be calculated using the formula: Work = Force x Distance. In this case, the force is 5000 N and the distance is 5 meters. Therefore, the work required to lift the log 5 meters would be 5000 N x 5 m = 25000 Joules.
The work done is calculated as the force applied multiplied by the distance moved in the direction of the force. In this case, the work done is (15 , \text{N} \times 3.0 , \text{m} = 45 , \text{J}).
