Subpart 4: CALCULATE NUMERICAL VALUES The mass of the block on the table is 4 kg and the hanging mass is 1.2 kg. (i) Calculate the magnitude of the acceleration of m₂. a = = 2.26 m S² (ii) Calculate the tension force in the string. T= 190 N (iii) Find the speed with which the hanging mass hits the floor if it starts from rest and is initially located 1.2 m from the floor. V= m S
Gravitational force
In nature, every object is attracted by every other object. This phenomenon is called gravity. The force associated with gravity is called gravitational force. The gravitational force is the weakest force that exists in nature. The gravitational force is always attractive.
Acceleration Due to Gravity
In fundamental physics, gravity or gravitational force is the universal attractive force acting between all the matters that exist or exhibit. It is the weakest known force. Therefore no internal changes in an object occurs due to this force. On the other hand, it has control over the trajectories of bodies in the solar system and in the universe due to its vast scope and universal action. The free fall of objects on Earth and the motions of celestial bodies, according to Newton, are both determined by the same force. It was Newton who put forward that the moon is held by a strong attractive force exerted by the Earth which makes it revolve in a straight line. He was sure that this force is similar to the downward force which Earth exerts on all the objects on it.

Subpart 1: Draw FBDs
In your notebook, draw free body diagrams for m, and m₂ using the template as shown below. The
forces acting on the system are weights of the blocks, m,g, and m₂g, the tension in the string T and
the normal reaction N₁ of the table on m₁.
