Conceptual Question: Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?

Can you please help me with this question

Describe the force you would apply to an object on a very low friction track to produce the following position vs. time graph. Include the direction of the force and whether it is changing (for example, increasing or decreasing), constant, or anything else relevant to the motion. Explain reasoning

You are asked to double the acceleration of a billiard ball (pool ball). Describe how you will have to change the original force to do this. Explain/show how Newton's 2nd law helps you to get the correct answer. Use complete sentences! A. You will have to apply 2 times the original force B. You will have to apply 3 times the original force C. You will have to apply only 1/2 the original force D. It is not necessary to change the original force

Learning Goal: Once you have decided to solve a problem using Newton's 2nd law, there are steps that will lead you to a solution. One such prescription is the following: • Visualize the problem and identify special cases. Isolate each body and draw the forces acting on it. Choose a coordinate system for each body. Apply Newton's 2nd law to each body. • Write equations for the constraints and other given information. • Solve the resulting equations symbolically. ● Check that your answer has the correct dimensions and satisfies special cases. ● ● ● • If numbers are given in the problem, plug them in and check that the answer makes sense. • Think about generalizations or simplifications of the problem. As an example, we will apply this procedure to find the acceleration of a block of mass m2 that is pulled up a frictionless plane inclined at angle with respect to the horizontal by a massless string that passes over a massless, frictionless pulley to a block of mass m₁ that is hanging…

Newton's Laws of Motion #2 Jumping to the Ground. A 75.0-kg man steps off a platform 3.10 m above the ground. He keeps his legs straight as he falls, but at the moment his feet touch the ground his knees begin to bend, and, treated as a particle, he moves an additional 0.60 m before coming to rest. (a) What is his speed at the instant his feet touch the ground? (b) Treating him as a particle, what is his acceleration (magnitude and direction) as he slows down, if the acceleration is assumed to be constant? (c) Draw his free-body diagram. In terms of the forces on the diagram, what is the net force on him? Use Newton's laws and the results of part (b) to calculate the average force his feet exert on the ground while he slows down. Express this force in newtons and also as a multiple of his weight.

Cars now have steering columns and front bumpers that collapse upon impact in a front end collision. Using the kinematics of ACCELERATION and F=MA explain why that REDUCES the forces on a person in the car in a front end collision.   2. Give THREE examples of FORCES in your future career (in MD, DO, DDS, PA, PT, Envir. Sci, etc.) AND the physical mechanisms that produce those forces (such as muscles powered by ATP and explain how the ATP produces those forces, or the forces on the walls of blood vessels exerted by systolic and diastolic blood pressure.)   (Pls help me answer those two parts in the minimum word caunt of 200 words Pls I reallt need help with this!!)

PHYSICS! WRITE THE COMPLETE SOLUTIONS LEGIBLY. NO LONG EXPLANATION NEEDED. UPVOTE WILL BE GIVEN! MULTIPLE CHOICE A is 10 kg on 30 degrees incline. The coefficient of kinetic friction is 0.20. Block B is 8.0 kg. The acceleration of B is: a. 2.6m/s2, down b. 2.6m/s2, up c. 0.69m/s2, down d. 0.69m/s2, up e. 0
