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
It depends on the weight. The work required in joules (kg*m2/s2) is equal to the force applied in newtons and the displacement, or distance, in meters. Thus, for an object that weights 1 N (multiply the weight of the object by the gravitational acceleration, 9.81 m/s2 to transfer to newtons) will require 1 N * 3 m = 3 J. Thus, the formula for work is: W = Fd "W" is the work done on the system. "F" is the force in newtons "d" is the displacement (or distance) of the object in meters.
700 x 4 = 2,800 newton-meters = 2,800 joules
78*6*9.8 N = 4586.4 N
Two meter sticks taped together LOL.
Well a bookcase or chair would be a perfect answer
To calculate the work done when lifting an object, you can use the formula: work = force × distance. The force required to lift an object is equal to its weight, which is mass × gravity. So, you would need to know the mass of the object to calculate the work done when lifting it 1600 meters.
The work done to lift the object is equal to the force applied multiplied by the distance moved in the direction of the force. In this case, the work done would be 500 newtons x 8 meters = 4000 joules.
minimum 150 joules
25 joule
12250
The work done on an object is calculated by multiplying the force applied by the distance moved in the direction of the force. In this case, the work done would be 18 joules, which is equal to 6 newtons multiplied by 3 meters.
C.50 j
When an object is thrown upward, work is done against gravity as the object moves upward. The amount of work done is equal to the force applied to lift the object multiplied by the distance it moves vertically.
The work done on the crate would be 40 joules (work = force x distance).
work done=m*g*h=53*9.81*7=3.63951 kJ where: m is mass (kg) g is acceleration due to gravity h is lift displacement
It depends on the weight. The work required in joules (kg*m2/s2) is equal to the force applied in newtons and the displacement, or distance, in meters. Thus, for an object that weights 1 N (multiply the weight of the object by the gravitational acceleration, 9.81 m/s2 to transfer to newtons) will require 1 N * 3 m = 3 J. Thus, the formula for work is: W = Fd "W" is the work done on the system. "F" is the force in newtons "d" is the displacement (or distance) of the object in meters.
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).
