A certain rocket can do a maximum of 2.00 times 10^10J of work on a 500-kg object. What is the maximum distance from the center of the Earth the object can reach?

What is the speed of the object when it is 1.5 x 10 m from the center of the Earth?

4x10^6m

Explanation:

Gravitational potential energy(j)=mass(kg) x gravitational field strength(10N/Kg) x height(m)
2 x 10^10 = 500 x 10 x height
height= (2 * 10^10)/(500 * 10)
= 4x10^6m
