A smaller student of mass m= 40 kg hangs from a light rope which passes over a large but massless pulley. The other end of the rope is held by a larger student of mass M= 50 kg who is in contact with the floor. a)With the smaller student hanging at rest, what is the force that the floor exerts on the larger student? For parts (b) and (c), the smaller student climbs up the rope so that he accelerates at 1.9 m/s2.
What is the tension in the rope as the smaller student climbs and accelerates?
While the smaller student climbs and accelerates, what is the force that the floor exerts on the larger student?
d)What minimum acceleration must the smaller student have if he is to cause the larger student to lose contact with the floor?
