How much work is needed to raise a 110-kg load of bricks 12 m above the ground to being under construction?
work in joules= weight*height
where weight is mass*9.8m/s^2
To find the amount of work needed to raise a load of bricks, you can use the formula:
Work = weight * height
First, we need to calculate the weight of the load. The weight is given by the formula:
Weight = mass * acceleration due to gravity
Given that the mass of the load is 110 kg, and the acceleration due to gravity is approximately 9.8 m/s^2, we can calculate the weight as:
Weight = 110 kg * 9.8 m/s^2 = 1078 N (Newtons)
Next, we need to calculate the height. It is given as 12 m in the question.
Now, we plug the calculated values of weight and height into the formula for work:
Work = 1078 N * 12 m = 12,936 Joules
Therefore, the amount of work needed to raise the 110 kg load of bricks 12 m above the ground is 12,936 Joules.
