How much work needs to be done to lift a 500kg mass from the ground to a height of 10 meters?

The work done to lift the 500kg mass to a height of 10 meters is given by the formula: work = force x distance. In this case, the force required to lift the mass against gravity is equal to its weight, which is given by: force = mass x gravity. Therefore, the work done would be: work = 500kg x 9.8m/s^2 x 10m = 49,000 Joules.
