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
W = f.s Work = force x distance w in neuton metres

power=work done/time interval
The work done to lift an object is given by the formula: work = force x distance. Since work is given as 3 kJ (3000 J) and distance is given as 3 mm (0.003 m), the force required to lift the object can be calculated. Using the formula for force (mass x gravity), you can determine the mass of the object that requires this work to lift it.

To calculate work done when given mass and power, you need to know the force applied and the distance over which the force is applied. Work done is calculated as the product of force, distance, and the cosine of the angle between them. Power is the rate at which work is done, so you can calculate it by dividing the work done by the time taken to complete the 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
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 formula for work done against gravity is given by W = mgh, where W is the work done, m is the mass of the object, g is the acceleration due to gravity, and h is the height the object is raised.
The work done to lift the 500kg mass to a height of 10 meters is given by the formula: work = force x distance. In this case, the force required to lift the mass against gravity is equal to its weight, which is given by: force = mass x gravity. Therefore, the work done would be: work = 500kg x 9.8m/s^2 x 10m = 49,000 Joules.
To find the distance the apple was lifted, we can use the formula for work: work = force × distance. The force needed to lift the apple would be its weight, which equals mass × gravitational acceleration (9.8 m/s^2). So, we can calculate the distance by rearranging the formula: distance = work / (mass × gravitational acceleration). Plugging in the values (2 J of work, 0.18 kg mass), we get distance = 2 J / (0.18 kg × 9.8 m/s^2) ≈ 1.08 meters.
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.
Force on the box = (weight) = (mass) x (gravity)Work = (force) x (distance) = (mass x gravity) x (distance)Mass = (work) / (gravity x distance)= (5000) / (9.8 x 16) = 31.888 kg (rounded)
