I need some assistance in answering this:
A force of 30N accelerates a 2.0 kg object from rest for a distance of 3.0 m along a frictionless horizontal surface. The force then changes to 15N and acts for an additional 2.0 m. What is the final kinetic energy of the object?
Would the final Kinetic Energy just be the kinetic energy of both situations added together?
