Dean Fabien exerts a force P on the car at an angle a = 20°. The 1760 kg car has front wheel dri Prof. Schulz, the driver, spins the front wheels, and the coefficient of kinetic friction µk = 0.02. [ Think about what direction friction should be drawn. The car is in reverse...] The combined eff of friction and a snow pile behind the rear tires exerts a horizontal resting force S. Getting the c to move requires overcoming a resisting force S = 420 N. а. What force P must Dean Fabien exert? b. What value of a will minimize the magnitude of P that Dean Fabien would have to exert overcome the resisting force S = 420 N? [Hint: Think calculus!] What force must he exert (at this new angle)? С.

What is the degree of freedom of the two questions

The wind chill (i.e. how cold it actually feels) is given by W(T,v) = 35.74 +0.6215T – 35.75v0.16 + 0.4275Tv0.16 degrees Fahrenheit when the actual air temperature is T degrees Fahrenheit and the wind speed is v miles per hour.

For the last portion, why do you divide by two?

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…

Solve it pleas

Please do the last three questions (2, 3 and 4)! Thank you in advance!  A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center.  1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs?  2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction?  3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?)  4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did…

Pls answer correctly and corresponding to what is given in the image attached. The instructions are already in the image. Thank you
