A bulldozer does 30000 joules of work to push a boulder a distance of 20 meters. How much force is applied to push the boulder?

Work= Force(Distance)
30000= F(20)/20
Force= 1500

A crane does 62500 joules of work to lift a boulder a distance of 25 meters. How much did the boulder weigh?
We know that 62500 joules of work was done against gravity of a distance of 25 meters. We need find the force that the crane applied to the boulder. We know that work is equal to the force times the displacement so: W=FΔd 62500=F(25) <-Now divide both sides by 25 to isolate "f" 2500=F We now know that the crane applied a force of 2500 Newtons to move the boulder. We know that this was done in the opposite force of gravity which means that we can use the formula for acceleration due to gravity to find the mass: Fg=gm <- where Fg is the force due to gravity, g is the acceleration due to gravity and m is the mass of the object. 2500=9.81m <- divide both sides by one to find the mass 254.84=m <- this is the mass in kilograms of the boulder 260 kg would be the correct answer due to the lack of significant figures in the distance measurement .
How much work is done on A 50 newton rock that you lift 10 meters staright up?
Just multiply the force times the distance. The answer is in joules.
What distance was an object moved by a force of 45 N if the work was 675 Joules?
The distance moved by the object can be calculated by dividing the work done by the force applied. In this case, the distance is 15 meters.
How many joules of work is being done when a 700 newton refrigerator is lifted straight up a distance of 4 meters?
Work is force x distance = 700 x 4 = 2800 Joules
Force equals mass times what?
Work. The force times the distance over which the force is applied is equal to the work. Work is measured in joules.

Just multiply the force times the distance. The answer is in joules.
How do you convert joules to cm?
It isn't possible. Joules is the measure of energy and cm is a measure of distance.
What distance was an object moved by a force of 45 N if the work was 675 Joules?
The distance moved by the object can be calculated by dividing the work done by the force applied. In this case, the distance is 15 meters.
Convert 355 nanometers to Joules?
It's impossible. Nanometers are units of distance and Joules are units of energy.
How many joules of work is being done when a 700 newton refrigerator is lifted straight up a distance of 4 meters?
Work is force x distance = 700 x 4 = 2800 Joules
What is the formula to find joules?
To find joules, you have to multiply the force or newtons by distance in meters.
Force equals mass times what?
Work. The force times the distance over which the force is applied is equal to the work. Work is measured in joules.
An object with a mass of 21 kg is lifted through a distance of 7 meters how much work is done?
Work = (force) x (distance) = 7 x 2.4 = 16.8 joules
How much work is done when a 115 g tomato is lifted 14.5m?
Work = Force applied over distance. So, distance is 14.5m, but how much force is applied? Force is equal to mass times acceleration, usually due to gravity. So, the force the tomato applies is .115kg * 9.81 m/sec2 = 1.12 Newton's. The work then is 16.2 Joules.
What did James Joules do in science?
James Joules created a method in which work is calculated. work(joules) equals force(newtons) times distance(meters) or j=n times m.
If you exert a force of 10.0 n to lift a box a distance of 0.9 m how much work do you do?
Work done equals force times distance, so 10.0 times 0.9 is 9 joules.
