A stonemason lifts boulder weighing 80 neutrons from the ground onto 1.50 meter wall in 2.0 seconds. How much work does he do
To calculate the work done by the stonemason, we can use the formula:
Work = Force x Distance
First, let's calculate the force required to lift the boulder. We know that the weight of the boulder is equal to its mass multiplied by the acceleration due to gravity. Therefore, we can calculate the force as:
Force = Weight = mass x acceleration due to gravity
Given that the weight is 80 neutrons and the acceleration due to gravity is 9.8 m/s², we have:
Force = mass x acceleration due to gravity
Force = 80 x 9.8
Force = 784 N
Now that we have the force, we can calculate the work done by the stonemason. We know that he lifts the boulder to a height of 1.50 meters. Therefore, the distance is 1.50 meters. Using the formula, we have:
Work = Force x Distance
Work = 784 N x 1.50 m
Work = 1176 Joules
Therefore, the stonemason does 1176 Joules of work to lift the boulder onto the 1.50 meter wall.
