Concept explainers
Draw separate free-body diagrams for each block and for the spring immediately after release. Indicate separately the vertical forces (perpendicular to the table top) and the horinra1 forces (parallel to the table top). Clearly label all forces.
Identify all the
The free body diagram of block and spring.
Explanation of Solution
Introduction:
Newtonian mechanics states that force never occurs singly in nature. Force is the mutual interaction between two bodies. The mutual forces are always equal and opposite in direction.
When the block is being apart, the spring force is acting towards the equilibrium position, and the block is coming towards each other as the spring is compressed.
In the vertical direction, force is acting on the block due to gravity.
The free body diagram in the vertical direction is shown in figure 1.
Figure 1
The free body diagram in horizontal direction is shown in figure 2.
Figure 2
Conclusion:
Therefore, the free body diagram in the vertical and horizontal direction is shown in Figures 1 and 2 respectively.

- Suppose your car was mired deeply in the mud and youwanted to use the method illustrated to pull itout. (a) What force would you have to exert perpendicular tothe center of the rope to produce a force of 12,000 N on thecar if the angle is 2.00°? In this part, explicitly show how youfollow the steps in the Problem-Solving Strategy for Newton’slaws of motion. (b) Real ropes stretch under such forces.What force would be exerted on the car if the angle increasesto 7.00° and you still apply the force found in part (a) to itscenter?arrow_forwardSuppose that you pulled the wooden box up the inclined plane at a constant speed using the spring scale. Using what you know about friction and the forces that would act on the box in such a situation, derive an equation for Uk in terms of the mass of the box m, the scale reading F, and the angle of theta. Show your equation first in a form that clearly shows the relationships of the forces, and then in a form solved for Uk. Explain your reasoning, and draw and label a diagram as part of your answer. (Coefficient of friction lab) Uk= coefficient of kinetic frictionarrow_forwardFrom the figure below, what is the net force acting on block Y?arrow_forward

Explain It it moves describe the motion. At what point along the road is the string attached?arrow_forwardIn 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.

- Monkey D. Luffy is sailing together with his crew, the “Straw Hat Pirates” in the West Philippine Sea. Thewind is quite strong and is exerting a 400N force on their sailboat “Thousand Sunny” directed to the south.The waves are also exerting a force of 208N westward.

- Help please. Teacher hasn't returned my work on this yet, and we're having a quiz on Monday. A 2.75-kg cat moves in a straight line (x-axis). The graph on the right shows the x-component of the cat’s velocity as a function of time. What is the net force on the cat? a. 0b. 27 Nc. 11 Nd. 2 N The maximum net force occurs during the time interval a. t = 0 to t = 10 secondsb. t = 6 to t = 10 secondsc. t = 2 to t = 6 secondsd. t = 0 to t = 2 seconds The net force on the cat is equal to zero between the time intervala. t = 6 to t = 10 secondsb. t = 2 to t = 6 secondsc. t = 0 to t = 10 secondsd. t = 0 to t = 2 seconds Thanks!arrow_forwardHow does Newton’s third law relate to the conservation of momentum? Cite an example. Useyour own sketches to help illustrate your response. please who work and illustration for me to understand thank youarrow_forwardPlease make a lab report (Newton's law) Abstract:- The goal for this experiment is to show that the acceleration is directly proportional to the net force in part A. And part B, we need to show the acceleration is inversely proportional to the mass, and the acceleration is directly proportional to the product of Force and one over mass.
