In a futuristic scenario, you are assigned the mission of making an enemy satellite that is in a circular orbit around Earth inoperative. You know you cannot destroy the satellite, as it is well protected against attack, but you can try to knock it out of its orbit so it will fly away and never return. What is the minimum amount of work W applied to the satellite that is required to accomplish that? The satellite's mass and altitude are 993 kg and 243 km. Earth's mass and radius are 5.98 × 1024 kg and 6370 km.

You have two 1500 kg masses 80.0 m apart. What is the gravitational potential energy of this system? Assume U= 0 for infinite separation of the three masses.

Taking the surface of Earth as reference level, how high above the ground does a 65-kg flying witch on a broomstick possess 7.1×103 J of gravitational potential energy?

The 50 kg block slides down the 2m high ramp. At some point, the block is .5 meters above the ground. What is its kinetic energy and potential energy of the block at that point? Keep in mind, the sum of the potential energy and kinetic energy has to be a constant value at any point on the ramp. We are ignoring any frictional effects.

The three spheres in the figure, with masses mA = 75 g, mB = 9 g, and mc = 23 g, have their centers on a common line, with L = 23 cm and d = 4 cm. You move sphere B along the line until its center-to-center separation from C is d = 4 cm. How much work is done on sphere B(a) by you and (b) by the net gravitational force on B due to spheres A and C? B L ·d C

If a 1000 kg car is exiting a highway through an above-the-ground ramp of 5.0 m radius at 12 m/s, what is the potential energy?

The Elf on the Shelf has mass 0.500 kg and is sitting on a shelf some height y above the ground. If the gravitational potential energy is 49.0 J, what is y?

Large meteors sometimes strike the earth , converting most of their kinetic energy into thermal energy. what is the kinetic energy of a 10^9 kg meteor moving at 25.0 km/s?
