Two blocks are connected by a massless rope. The mass of the block on the table is m1=5.5 kg and the hanging mass is m2 = 1.2 kg. The table and pully are frictionless. Write an equation for the speed at which the hanging mass hits the floor if it starts falling from rest in terms of the acceleration a, and the distance it has to fall to reach the floor d. Use this equation to find the speed if it starts falling from rest and is initially located 1.1 meters above the floor, give the answer in meters per second.

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
