Marty Mcfly is riding a hover board (futuristic skateboard that flys with no rolling resistance) while being towed by a Delorean. Thoughout this problem you may assume the rope is of negligable mass. Marty's mass is my. 1. If the Delorean is traveling at a constant speed ep and there is no air resistance, with what force does Marty need to hold onto the rope? 2. If there is air resitance of magnitude FA pushing back on Marty, with what force does he need to hold the rope. 3. If there is air resitance of magnit ude FA and the Delorean is accelerating forward at acceleration a, with what force does Marty need to hold the rope. 4. Is the magnitude of the force that the Delorean pulls the rope with greater, smaller, or the same as the force Marty holds the rope with? Explain why.
