The work done to push the box across the floor is 50 N * 30 m = 1500 J. The work done to lift the box is mgh = 10 kg * 9.8 m/s^2 * 6 m = 588 J. Therefore, the total work done is 1500 J + 588 J = 2088 J.
The work done is 2 joules. Work is calculated by multiplying the force exerted (1 newton) by the distance moved in the direction of the force (2 meters).
2,088 J
To calculate the increase in potential energy for each book, you multiply the force applied by the distance lifted. For the 20-newton book: 20 N * 0.5 m = 10 Joules. For the 25-newton book: 25 N * x = 10 Joules (where x is the height). Solving for x, x = 0.4 m.
The work done can be calculated using the formula: Work = force x distance. In this case, Work = 20 N x 5 m = 100 joules. Therefore, 100 joules of work are done when a 20 newton box is lifted 5 meters off the floor.
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.

The work done is 2 joules. Work is calculated by multiplying the force exerted (1 newton) by the distance moved in the direction of the force (2 meters).
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.

Have the required medical exam and take the test results to DMV.
The work done can be calculated using the formula: Work = force x distance. In this case, Work = 20 N x 5 m = 100 joules. Therefore, 100 joules of work are done when a 20 newton box is lifted 5 meters off the floor.
700 x 4 = 2,800 newton-meters = 2,800 joules
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.
Force x distance = 100 x 2 = 200 newton-meters = 200 joules.
In this case, work is the product of force and distance. (This assumes that both are in the same direction, and that the force doesn't change.)
In modern times, the t80 and t90 both require its barrel lifted the t34 also required it
