The free-fall acceleration on the surface of planet a is about one tenth of that on the surface of planet b. if the radius of planet a is a quarter of the radius of planet b (rb/4), find the ratio of their average densities?

How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.
