Which best explain the function of the pulley in the experiment on the vector addition of forces? Pulleys were used to know the tension in the string that is the same magnitude with the weight of the hanging mass and have an adjustable direction of the equilibrant. Pulleys were used to have an adjustable direction in locating the resultant force. O Pulleys were used to hang the masses. O Pulleys were used to neglect the friction between the string and the pulley.

This problem concerns the concept of tension in a rope. Consider a rope subjected to a pulling force on its two ends as shown in (Figure 1). The rope is stationary. An arbitrary point P divides the rope into a left-hand segment L and a right-hand segment R. Assume that segment R exerts a force of magnitude TTT on segment L. What is the magnitude FLRFLRF_LR of the force exerted on segment R by segment L? Give your answer in terms of T and other constants such as g. F_LR = ?
Shown to the right is a block of mass m sitting on a ramp that makes an angle θ with the horizontal. This block is being pushed by a horizontal force F. The coefficient of kinetic friction between the two surfaces is μ. a) Write an equation for the acceleration of the block up the ramp using variables from the problem statement together with g for the acceleration due to gravity.
In the figure below, a block of mass M hangs at rest. The rope that is fastened to the wall is horizontal and has a tension off 52 N. The rope that is fastened to the ceiling has a tension of 91N and makes an angle theta with the ceiling. What is the angle theta? What is the mass M? You MUST draw all the force vectors on the figure with their corresponding unit vectors( i , j ,k ) and then write the relation between forces based your sketches. Show your complete solution
Using differential equations solve the problem: A long, very smooth board is inclined at an angle of 10 with the horizontal. A weight starts from rest 10 ft from the bottom of the board and slides downward under the action of gravity alone. Find how long it will take the weight to reach the bottom of the board and determine the terminal speed.
A man pulls a crate with a rope. The crate slides along the floor in the horizontal direction (x direction). The man exerts a force of 50 N on the rope, and the rope is at an angle 0. Described how the force components (Fx,Fy) change as the angle increases from 0 degrees to 90 degrees and use your graph to explain your answer. Give a detailed explanation of the forces at 0= 0, 45degrees, and 90 degrees. please show a sample calculation at one angle for both components.
please help i answered the questions i just need to draw all the forces acting on the box do you mind helping me draw that?

Background: A full non-uniform circular motion We are going to have an object completing a full circle. A smart-cart was swiveled in the vertical (i.e. in front of us). The cart’s mass is ~240 grams and is hanging from a 0.5 m inextensible light string. In this experiment, the time in seconds and force of tension in Newtons for the smart-cart was measured. a) Find an algebraic equation that relates the minimum/maximum tension to the minimum/maximum linear speed so that the speed magnitudes may be estimated. b) What would be a good way to approximate the linear acceleration at a given time? (i.e. ~3.25 s, which is approximately halfway between the minimum and maximum tension values)
Determine the fit functions that best represent the position vs. time graphs in the x and y directions. Determine the acceleration as the block slides down the track for a given angle. Graph the magnitude of the kinetic frictional force versus the magnitude of the normal force for one block mass and the different angles you used. How does the magnitude of the kinetic frictional force on an object depend on the normal force on the object? What role does the kinetic frictional force play as the crates go sliding down the ramp?
What equation would you need to find the final velocity of the can rolling down the incline? Does it have anything to do with finding average velocity first? Use kinematics to derive a “final velocity” equation (we can call it “Equation 4”) for vfinal using L, g, t and θ. (Note that you may not need all of the variables.) Show your work below and put a box around your answer. (Do your work on scratch paper and copy the “clean” version here.) Given: g = gravitational acceleration θ = angle of incline t = time to roll down L L = diagonal length of the rolling distance down the incline Note: a  g sin . The object is rolling, not sliding. Requested: vfinal = final velocity of rolling object at bottom of incline
