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.

The plum pudding model of the atom states that ?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
