You cannot. You do not have the necessary information.
First Find the Force Acting on Body take a = 9.8m/s F=ma Second Work Done = Force x Displacement Answer will be in Joules
W=Fd so when you divide both sides by Force and Work and take the reciprocal you get the equation F=W/d -Joshua Garrison
You can't. Work is (force) times (distance), so you have to know something about the force. Just knowing the mass doesn't tell you anything about the force ... unless there's actually something else about the mass that you've overlooked.
W = f.s Work = force x distance w in neuton metres
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 can find the output force by dividing the work done by the input force by the efficiency. This formula is: Output Force = Work / (Input Force * Efficiency).
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 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 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.
If you search Wikianswers, you can find lots of questions and answers on force, weight, acceleration, work, and energy.
Work W=Pt power times time, W = FVt.

W=Fd so when you divide both sides by Force and Work and take the reciprocal you get the equation F=W/d -Joshua Garrison
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
