1. Determine whether the statements below are true or false: a. Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. A person's mechanical stability can be increased by lowering one's center of c. mass (such as when one bends their knees).
