A0.2-kg steel ball is dropped straight down onto a hard, horizontal floor and bounces straight up. the ball's speed just before and just after impact with the floor is 10 m/s. determine the magnitude of the impulse delivered to the floor by the steel ball.

Explanation:

Given

mass of steel ball

initial speed of ball

Final speed of ball (in upward direction)

Impulse imparted is given by change in the momentum of object

therefore impulse J is given by

so magnitude of Impulse =4 N-s

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.

explanation:

the bal will not change its velocity.
