How much work is required to lift a 5.2-kg concrete block to a height of 3.1 m?
m g h = 5.2 * 9.81 * 3.1 Joules
To calculate the work required to lift the concrete block, we can use the formula: Work = Force × Distance.
In this case, the force required to lift the block will be equal to its weight. The weight of an object is given by the formula: W = m × g, where m is the mass of the object and g is the acceleration due to gravity, approximately 9.8 m/s².
So, let's calculate the weight of the concrete block: W = 5.2 kg × 9.8 m/s² = 50.96 N.
Now we have the force required to lift the block. The next step is to calculate the distance over which the block is lifted, which is 3.1 m.
Finally, we can calculate the work required: Work = Force × Distance = 50.96 N × 3.1 m = 158.276 J.
Therefore, it would require approximately 158.276 Joules of work to lift the 5.2 kg concrete block to a height of 3.1 m.
