How much work is done to lift a 50.0 kg block 7.00 meters, using g=9.81 m/s²?

To find the amount of work done in lifting a block, you can use the formula for work, which is given by the equation:

[ \text{Work} = \text{Force} \times \text{Distance} ]

In the context of lifting an object against the force of gravity, the force exerted is equal to the weight of the object. The weight can be calculated by multiplying the mass of the object by the acceleration due to gravity.

Here, the mass of the block is 50.0 kg and the acceleration due to gravity is approximately 9.81 m/s². Therefore, the weight (or force) of the block can be calculated as follows:

[ \text{Weight} = \text{mass} \times g = 50.0 , \text{kg} \times 9.81 , \text{m/s}² = 490.5 , \text{N} ]

Now, to compute the work done in lifting the block to a height of 7.00 meters:

[ \text{Work} = \text{Weight} \times \text{Distance} = 490.5 , \text{N} \times
