You don't
The work done by the crane is given by the formula: Work = Force x Distance. Assuming the force required to lower the material is equal to its weight, the work done would be equal to the weight (Force) multiplied by the distance. If the weight of the material is known, multiply it by 150 meters to find the work done in lowering the material.
You cannot. You do not have the necessary information.
To calculate distance with velocity and weight, you can use the equation for work: Work = Force x Distance. The force can be calculated by multiplying the weight with gravity. Velocity can then be used to determine the time it takes for the object to travel that distance using the equation Distance = Velocity x Time.
weight x distance = work
The formula for finding work is: Work = force X distance. To find distance, you must divide both sides by force. After simplifying the equation, the new equation will read: distance = work divided by force
The power of the machine can be calculated using the formula Power = Work/Time. Given that Work = Force x Distance, and the force required to lift the object will be its weight (N), the power can be calculated using the force (weight of object) and the distance it is lifted in the given time frame.
First you have to find the force F=(mass/weight of object)*(9.8) Once you find force Work=(Force)*(Distance) Your answer will be in joules
The work done is given by the formula Work = Force x Distance. Rearranging this formula we find Distance = Work / Force. Plugging in the values given, we get Distance = 68 joules / 4 newtons = 17 meters. So, the crate was moved 17 meters.
I'm fairly sure that you can't. Not without the acceleration or the time, at least.
The work done to lift the weight is given by the formula: work = force * distance. Setting the work as the weight times the height raised, we can calculate the force required as follows: force = work / distance = (2000 N * 1 m) / 4 m = 500 N. This means a force of 500 N was required to raise the weight.
The work done to lift a weight is given by the formula: work = force x distance. In this case, the force is equal to the weight of the object (50kg x 9.8 m/s^2 = 490 N), and the distance is 3.0m. Therefore, the work required to lift a 50kg weight 3.0m is 1470 joules.
To find distance in the work formula, you can rearrange the formula to distance equals work divided by force. This allows you to calculate the distance by dividing the work done by the force applied.
