A rocket moving in free space has a speed of 2390 m/s relative to the Earth. Its engines
are turned on, and fuel is ejected in a direction
opposite to the rocket motion at a speed of
3070 m/s relative to the rocket.
What is the speed of the rocket relative to
the Earth once its mass is reduced to one half
its mass before ignition?
Answer in units of m/s.
part 2 of 2
What is the thrust on the rocket if it burns
fuel at the rate of 51.5 kg/s?
Answer in units of N.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
