Question:

PLEASE HELP! IF YOU ANSWER ALL PARTS TO MY QUESTION I WILL DO ANY 20 OF YOUR QUESTIONS AT ANY TIME!!! I WILL EVEN DO A TEST FOR YOU!

We all know the formula for work: W = FD. But what about t the work-energy theorem? This theorem involves kinetic energy, which of course is implied in the formula for work as well. (1) What is the work energy theorem? (2) Write the formula for the theorem. (3) Use the formula to answer the question: According to the work-energy theorem, between what two points does the roller coaster car do the most work? The roller coaster car has mass 20 kg.

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
