Question

6. Calculate Work How much work was done to lift a 1000 kg block to the top of the Great Pyramid, 146 m above the ground?

Answer 1

given,
mass of the object = 1000 kg 
height = 146 meter acceleration due to gravity = 9.8 m/s²
but for easy calculation we will take acceleration due to gravity as
= 10 m/s² 
therefore work done ,
W = m * g * h
W = 1000 * 10 * 146 
W = 1460000 J
W = 1.46 *  10⁶ J
therefore work done = 1.46 * 10⁶J
