•• cp two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. block aa has mass 15.0 kg, and block bb has mass mm. a constant horizontal force f=60.0 nf=60.0 n is applied to block aa (fig. p4.38). in the first 5.00 s after the force is applied, block aa moves 18.0 m to the right. (a) while the blocks are moving, what is the tension tt in the rope that connects the two blocks? (b) what is the mass of block b?
