Two blocks are connected by a massless rope as shown below. The mass of the block on the table is m1 = 5.6 kg and the hanging mass is m2 = 1.1 kg. The table and the pulley are frictionless. Write an equation for the speed at which the hanging mass hits the floor if it starts falling from rest. Give your answer in terms of the acceleration a and the distance it has to fall to reach the floor d.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is transformed ⇒ as it changes into other forms of energy.
