Two blocks are connected by a massless rope as shown below. The mass of the block on the table is 4.9 kg and the hanging mass is 1.9 kg. The table and the pulley are frictionless. (a) Find the acceleration (in m/s2 ) of the system. (Enter the magnitude.) m/s2 (b) Find the tension (in N) in the rope. N (c) Find the speed (in m/s) with which the hanging mass hits the floor if it starts from rest and is initially located 2.1 m from the floor. m/s
