Jacob is riding his bike down a tall hill. At the top of the hill, he has 2800J of potential energy. At the bottom of the hill, when he is going the fastest, his kinetic energy measures 2650J. Which statement below is true? Question 5 options: The total amount of energy at the bottom of the hill cannot equal the amount at the top, because some of the energy is gained. The total amount of energy at the bottom is equal to the amount at the top, but some energy was converted into other forms due to friction. The total amount of energy at the bottom of the hill cannot equal the amount at the top, because some of the energy is destroyed. The total amount of energy at the bottom is equal to the amount at the top, but he gained some energy as he traveled due to a higher speed.
