In the Figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.3 kg, block B has a mass of 2.7 kg, and angle è is 26 °. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 27 cm and in ths block b is hanging down? i jus wanted to ask that difference PE=final KE means
mass of a*g*h-mass of b*g*hsin26=totalKE. is this right? bcause i m nt getting right answer. for a height should be h= 0.27cos26 and for b height=0.27? figure is wat u assumed that block b is hanging. bt i didn't gt right ans
