Problem: Skid and Mitch are pushing on a sofa in opposite directions with forces of 530 N and 270 N respectively. The mass of the sofa is 48 kg. The sofa is initially at rest before it accelerates. There is no friction acting on the sofa.
Part A: Calculate the acceleration of the sofa.
Part B: How long does it take the sofa to move 100 m?
Part C: What is the sofa's velocity at this point?
