Two blocks connected by a string are pulled across a horizontal surface by a force applied to one of the blocks, as shown to the right. The mass of the left block m1 = 1.9 kg and the mass of the right block m2 = 4.1 kg. The angle between the applied force and the horizontal is θ = 51°. The coefficient of kinetic friction between the blocks and the surface is μ = 0.35. Each block has an acceleration of a = 2.9 m/s2 to the right. a)Write an equation for the magnitude of the applied force F acting on the second block. Use variables from the problem statement as well as using g for the gravitational acceleration. b)Calculate the magnitude of the applied force F. Give your answer in newtons
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.
