A rope is attached to a box with mass 122 kg and Person A is pulling the box to the right on the floor. There is a frictional force between the floor and the box, and the magnitude of the tension force in the rope is 98 N. Now Person B comes into help person A. Person B pushes the box to the right with a force of 65 N. and the box accelerates at the rate of 0.75 m/s^2 to the right. Person A is pulling the box with the same constant force before and after Person B comes in to help. Assuming that the frictional force is also constant before and after Person B comes in. What is the magnitude of the frictional force between the box and the floor in the unit N? Answer to nearest whole number.
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.
