![]() When system is in motion, find the tension on the rope.įree body diagrams of boxes are given below. ![]() Since force acting on X is double of force acting on Y, a X=2a Yĥ. If masses of X and Y are equal find the acceleration of the X?(g=10m/s 2) PhD degree in physics, chemistry, materials science, chemical engineering and related disciplines Detailed knowledge of molecular dynamics simulation. Founded in 2008, Physics Help Forum is dedicated to free physics help and physics discussions, and our physics community welcomes students, teachers, educators, professors, scientists, and engineers. In the system given below ignore the friction and masses of the pulleys. Physics is the study of energy and matter in space and time and how they are related to each other. If the acceleration of the box X is 5m/s 2, find the acceleration of the box Y.įree body diagrams of boxes are given below Ĥ. As you can see in the picture given below, two boxes are placed on a frictionless surface. ![]() We apply Newton's second law on two boxes.ģ. The fifth in a series of six videos where we look at the key definitions that you need to learn for the National 5 Physics SQA exam, as well as any class tes. Find the acceleration of the boxes and tension on the rope. Friction constant between the surfaces is k=0,4. Picture given below shows the motion of two boxes under the effect of applied force. X component of force gives acceleration to the box.Ģ. We show the forces acting on the box with following free body diagram. Mass of the box is 2kg and surface is frictionless.
