To lift a 950-N load 3 meters requires (950 x 3) = 2,850 joules of energy.

The power is the rate at which the energy is delivered. It takes more power

to lift the load faster.

The power used to lift this load is (2,850 joules) divided by (the number of seconds it takes),

and the unit of the answer is watts.

Q: How much power is used if the 950 N person lifted 3 meters?

700 x 4 = 2,800 newton-meters = 2,800 joules

78*6*9.8 N = 4586.4 N

work done is = to force multiply by displacement here force is = 1000x10 N and dispacement is 75m = 75x104

The work done on the fallen tree would depend on the force applied, not just the distance lifted. Work is calculated as force multiplied by distance. Without knowing the force applied, we cannot determine the work done.

question 24 on penn foster is C.

The work done in lifting the tree is equal to the force applied multiplied by the distance it is lifted. The amount of work done would depend on the weight of the tree and the force required to lift it to a height of 2.75 meters above the ground.

78*6*9.8 N = 4586.4 N

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).

The work done to lift the box is equal to the force applied multiplied by the distance moved, which is 20 joules in this case (10 N * 2 m). Power is the rate at which work is done, so if the box is lifted in 1 second, the power required would be 20 watts (20 joules / 1 second).

The potential energy gained by the object is 1,000 Joules. Potential energy is calculated using the formula PE = mgh, where m is the mass of the object (10 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height the object is lifted (10 meters).
