**Educational Content: Free-Body Diagrams and Newton's Second Law**In this example, we are asked to set up free-body diagrams and equations for Newton's second law for two objects, A and B, which are interacting on a horizontal table. **Diagram Description:**- Object A is placed on top of object B.- Object B is in contact with the horizontal table.- A pull force is applied horizontally to object B.**Instructions:**1. **Free-Body Diagrams:** - **For Object A:** - Identify forces acting on A, including gravitational force (weight) acting downwards and the normal force exerted by B acting upwards. - Consider frictional force between A and B if A is resisting motion. - **For Object B:** - Include gravitational force acting downwards and normal force from the table acting upwards. - The pulling force acts horizontally on B. - Frictional forces may act between B and the table, as well as between A and B if there is a tendency for sliding.2. **Equations:** - Apply Newton’s second law (\( F = ma \)) to each object along the horizontal and vertical axes. - Remember to consider the different coefficients of friction for different surfaces.This exercise requires creating two free-body diagrams: one for block A and another for block B. These diagrams will help in visualizing and setting up the equations of motion for each object.

Please help with all parts, it is one question. A. Two blocks are positioned on surfaces, each inclined at the same angle of 50.3 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 4.97 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.200. Assume static friction has been overcome and that everything can slide.

A B Let's revisit a previous problem and add the force of friction. In the figure, block A has a mass of 2.67 kg. It rests on a smooth but not frictionless horizontal table and is connected by a very light horizontal string over an ideal pulley to block B, which has a mass of 2.82 kg. The coefficient of kinetic friction between block A and the table is 0.210. When block B is gently released from rest, how long does it take block B to travel 0.713 m? Be sure all quantities are expressed in standard units before calculating anything. Report your answer in seconds.
Lost in Space Context A space shuttle drifts through space. At one point, its motors are turned on for a certain amount of time, which exerts a force perpendicular to its initial trajectory. Your objective is to determine the speed vector of the shuttle when the engines turn off. Constraints The mass of the ship is known, as well as its initial speed.The length of time the motors are on is known.The force generated by the motor is known and assumed to be constant. Modelization Models the modulus of the final speed (in km/h) according to the known parameters. Then model the angle the shuttle will travel after the motors turn off. This angle is the smallest angle measured with respect to the initial direction. Then test your model with the following parameters: Initial velocity: 460 km/h; Shuttle mass: 2098000 kg; Engine ignition duration: 13 s; Net force of motors: 4700000 N.

Problem 2: A block with a mass of m = 1.5 kg rests on a wooden plank. The coefficient of static friction between the block and the plank is u, = 0.84. One end of the board is attached to a hinge so that the other end can be lifted forming an angle, 0, with respect to the ground. Assume the x-axis is along the plank as shown in the figure. m
GOAL Apply the concept of static friction to an object resting on an incline. PROBLEM Suppose a block with a mass of 2.50 kg is resting on a ramp. If the coefficient of static friction between the block and ramp is ng sin e 0.350, what maximum angle can the ramp make with the horizontal mg cos e e before the block starts to slip down? STRATEGY This is an application of Newton's second law involving an object in equilibrium. Choose tilted coordinates, as in the figure. Use the fact that the block is just about to slip when the force of static friction takes its maximum value, f. = 4n. SOLUTION Write Newton's laws for a static system (1) EF = mg sin e - u̟n = 0 in component form. The gravity force (2) EF = n - mg cos e = 0 has two components. Rearrange Equation (2) to get an n = mg cos 8 expression for the normal force n. Substitute the expression for n into EF, = mg sin 8 - H mgcos 0 = 0 → tan 8 =u. Equation (1) and solve for tan 0. Apply the inverse tangent function to get the answer.…

Between two ski hills, there is a valley. Hill l is 735m and the second hill is 625m. From point A to point B, a skier skis. The skier starts at rest at point A and finishes at rest at point B. Between the two points, the total length of the path is 4.11m with an average slope of 40 degrees from the horizontal. a) Sketch the free body diagram and show all the forces on the skier. Indicate the location where the gravitational potential energy is equal to zero on the diagram. b) assuming the system is skier and the earth, and there is friction involved between the ski and the snowy ground ( coefficient of kinetic friction), determine the thermal energy that is lost to the surrounding when the skier is skiing from point A to point B in terms of variables, m, L and theta c) Calculate the value of coefficient of kinetic friction between snow and ski which would make the skier stop at the top of the lower point B
