Question: We learn in introductory physics that when an object is dropped from rest its potential graviational energy ( PE ) is converted into kinetic energy
We learn in introductory physics that when an object is dropped from rest its potential graviational energy PE is converted into kinetic energy KE If there is no friction ie drag between the object and the air or water, or whatever the surrounding environment is composed of then conservation of energy tells us that the change in the object's PE is equal to its change in KE:In terms of relevant physical variables, this relationship is written aswhere m is the object's mass, g is the constant acceleration due to gravity, h is the object's height above some reference point, V is the object's velocity, and the subscripts and represent the initial and final states of the object, respectively.This classic falling object problem is often used to answer questions like, "What is the object's velocity right before it hits the ground?" Once we have a grasp of these simple falling object problems, it is interesting to try to answer new questions like, "What happens after the object hits the ground?" This question naturally leads to the study of collisions. For perfectly elastic collisions, no energy is lost and the upward velocity of the ball just after it hits the ground is exactly equal to the downward velocity of the ball just before it hits the ground. In this idealized scenario the ball will bounce all the way back up to its initial height and continue doing so forever; clearly, the elastic collision case does not describe real collisions.A more realistic mathematical model for a bouncing object leads us to the study of inelastic collisions. For inelastic collisions, the upward velocity of the object after rebounding off the ground is less than its downward velocity just before striking the ground. The ratio of the magnitudes of these velocities is called the coefficient of restitution Elastic collisions are described by and inelastic collisions are described by Leaving the details for your physics class, the total distance traveled by an object initially dropped from a height isNote that, interestingly, the mass of the object and the acceleration due to gravity have no effect on this result. We recognize the term in parenthesis as almost a geometric series. We can turn this into a geometric series by adding and subtracting ie effectively adding to z givingwhere n represents the number of bounces the object makes off the ground. The term might seem strange at firstdoes this somehow mean the object can possibly travel a negative distance? Test this expression for bounces to assure yourself that this negative term out front isn't an issue. The second term in the final expression for z is clearly a geometric serieswith Since we know we can use the general result for the infinite sum of a geometric series to show that the total distance traveled by the object isNote that the total distance traveled is infinite when which is the expected result when the collision is perfectly elastic, but converges to some finite value for any Your TaskWrite a function called BallBounce that takes in values for the initial height of a ball above the ground h and the coefficient of restitution between the ball and the ground e that does the following:Finds the total distance traveled by the object in the limit that the number of bounces goes to infinity. This value should be the first output of your function.Finds the number of bounces required for the ball to travel at least of the total distance it will travel. This value should be the second output of your function. Note that if the coefficient of restitution is very small, the ball will travel of the total distance after bounces ie during the initial fall to the groundDefine a row vector that stores the distance traveled as a function of the number of bounces. The last element of this row vector should be the distance traveled once the condition described above is met. This vector should should be the third output of your function. You can perform a preliminary check of this variable by making sure its first element corresponds to the distance traveled for bounces.h;e ;TotalDistBounceOut,z BallBouncehe
