what is the magnitude of the impulse i, in kilogram meters per second, the rock experienced during the bounce?

Impulse of force is the product of the resultant force and the duration of this force, if the force is constant. Impulse of force is the cause of changes to motion and therefore changes to momentum.The impact force is the product of the resultant force, ΣF, and the duration of that force, Δt, if the force is constant. Force impulses are responsible for changes in motion and therefore for changes in impulse.Momentum can be defined as a measure of a body's resistance to stopping. The terms pulse are interchangeable. The term momentum refers to the quantity that represents the net force effect on an object. A very important application of theImpulse is to increase safety and reduce injuries. Objects often need to stop above a certain initial velocity. That is, there is some predetermined momentum change.Learn more about Impulse here:- https://brainly.com/question/229647#SPJ4
