Joaquin and Susanna are pushing a cart containing sports equipment along one side of their local sports field. In section A, the cart is speeding up. In section B, the cart is rolling at a constant speed. In section C, the cart is speeding up again. In section D, the cart is rolling at a new constant speed. Then they think about how this data relates to what they learned in class about kinetic energy. Study the graph and then answer the questions. Question 1 a. In which section or sections is the cart's kinetic energy increasing? You might need to choose more than one answer.
The cart's kinetic energy is increasing in sections A and C.
