Transcription: This is our first problem with Newton's second law. We're given the mass of a car, 1500 kilograms, and we're told that the man must push the car with an acceleration of 0.03 meters per second squared to the east. And the question is, what's the force the man must use? How are we going to do that? Well, this is a pretty straightforward application of Newton's second law. According to the law, force equals mass times acceleration. We were given the mass, 1500 kilograms. so we can put that into the equation. We've also been given the acceleration, 0.03 meters per second squared east. So we'll put ...
