A large toy car is pushed horizontally by a spring, and the spring has a spring constant of 135 N/m. What is the mass of the toy car if compressing the spring 0.055 m (before the toy starts moving) causes it to reach a speed of 0.75 mis? (Note - the height of the toy does not change.) Solve the problem. (If you get the answer wrong, you can get 0.5 points for correct units.)
