A student uses a rubber band to shoot a 0.05kg toy car across a level floor. Imagine that no energy is transferred between the car and the floor or between the car and the air. The rubber band was stretched 0.03m. Before Toy car before it starts to move Toy car while it is moving Stretched rubber band Unstretched rubber band EPE KE ME Draw a graph below that best reflects the total energy of the system AFTER the rubber band is released? > Replay After KE GPE EPE ME ENERGY

A section of a roller coaster is designed like the picture below. A roller coaster car with a mass of 230.0kg is released from rest at the top of the hill at Point A to begin the ride. Assume that the reference level is set to the ground, and that energy is not lost to other forms (i.e. heat, sound, etc.). What is the total mechanical energy of this roller coaster car (at any point)?
