- A runner pushes against the track, as shown. (a) Provide a free-body diagram showing all the forces on the runner. (Hint: Place all forces at the center of his body, and include his weight.) (b) Give a revised diagram showing the xy -component form. (credit: modification of work by “Greenwich Photography”/Flicke)The contestant now pulls the block of ice with a rope over his shoulder at the same angle above the horizontal as shown below. Calculate the minimum force Fhe must exert to get the block moving. (b) What is its acceleration once it starts to move, if that force is maintained?1. Describe what you saw in the context of Newtons third law (equal and opposite forces): For every action, there is an equal and opposite reaction. Be careful here - where does the force of thrust come from? a. Which direction does the force of thrust point? Draw a free-body-diagram. Check that this makes sense given your answer to above.
- I need clear steps for this question, please. Show FBD and which coordinate system to use. Also, summing forces up using newton's 2nd law.First draw Free body diagram,then solve. (Strictly don't copy from othersites)1. Write Newton’s 2nd law for block A along the horizontal direction and solve for themagnitude of the force exerted by the rope on block A. 2. Write Newton’s 2nd law for block B along the horizontal direction and solve for itsunknown mass m. show the solution clearly
- Provide detailed explanations on how the formulas are derived with the help of 'free body diagrams'.Draw a free-body diagram of the setup and label the different forces. What is/ are the sum of forces? Make a mathematical expression for the sum of forces.2) Two people are pulling a boat through the water as shown in the Figure below. Each exerts a force of 600 N directed at an angle of 30.0° relative to the forward motion of the boat. If the boat moves forward with constant velocity, find the resistive ?⃗⃗force exerted by the water on the boat. Does your answer change if the boat is moving backward at constant velocity?
- Two masses B and C are connected with a string passing over a friction less pully, assuming the coefficient of friction between the table and block is μ=0.4 , and the acceleration of gravity g=9.81 m/s2. Solve the following questions (show all the steps of your calculations): A. Draw the free body diagram of the two masses.B. Find an expression of the acceleration of the two masses in terms of ?? and ??.C. Determine the tension in the rope in terms of ?? and ??.D. If ??= ʎ kg, ?? = (ʎ-5) kg, determine the acceleration of two blocks and the tension in the rope.(ʎ= the final two numbers of your ID +10, and, gravitational acceleration, g = 9.81 m/s2).Sketch free body diagrams for each object then apply Newton's second law on each object to calculate the Tension on the stringSuppose two children push horizontally, but in exactly opposite directions, on a third child in a sled. The first child exerts a force of 71 N, the second a force of 91 N, kinetic friction is 5.5 N, and the mass of the third child plus sled is 24.5 kg. Using a coordinate system where the second child is pushing in the positive direction, calculate the acceleration in m/s2.
