If a cement block that weighs 50 N must be raised to a height of 5 m, how much work must be done on the block?

Work=weight*heightincreased

To calculate how much work must be done on the block, we will use the formula: Work = weight * height increased, where the weight is the force of gravity acting on the block and the height increased is the vertical distance the block is raised.

Given that the weight of the cement block is 50 N and it needs to be raised to a height of 5 m, we can substitute these values into the formula.

Work = 50 N * 5 m

Now multiply the weight (50 N) by the height increased (5 m):

Work = 250 N⋅m

Therefore, the work that must be done on the block is 250 N⋅m (Newton-meters) or joules (J).
