the second question is also wrong. I should cancel this subscription. please answer it again with different person A block of mass m1= 4.00 kg is released from rest on an inclined plane that makes an angle theta= 30 degrees above the horizontal. The coefficient of kinetic friction between the block and the plane is Uk= 0.24. The block is attached to a second block of mass m2= 5.00 kg that hangs freely by a string that passes over a...

Your answer is partially correct. Try again. Two identical 0.12 kg blocks (labeled 1 and 2) are initially at rest on a nearly frictionless surface, connected by an unstretched spring, as shown in the upper diagram, where x2 = 0.05 m. Then a constant force of 7 N to the right is applied to block 2, and at a later time the blocks are in the new positions shown in the lower diagram, where xi = 0.02 m and x3...
