QUESTION:
In Fig. 8-60, the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.0 kg, block B has a mass of 2.0 kg, and angle u is 30#. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 25 cm? A B Figure 8-60 69.
ANSWER:Step 1 of 3The net force acting on the block B is given by,Implies, .............(1)The net force acting on the block A is given by,Implies, ............(2)Comparing equation one and two,Implies,\nGiven,Mass of the box A is,Mass of the box B is,The angle,So,
