I need help with this, please!

Free answer instructions: 1. At the top of the page write your name and problem version (A, B, or C) 2. Carefully read the problem 3. Write your solution to each sub-section separately (A, B, C) on paper Your solution can be turned in two ways: A. Scan or take a photo of your solution - make sure your scan is legible Make sure your file is in jpeg or pdf format (other formats will need to be converted). Upload your scanned solution using the "Choose a File" button beneath B. Turn in a hard-copy with your name on it to SRTC 134 by 2:20PM Version A A car of mass m negotiates a right hand 90" turn at constant speed v on a flat road such that the radius of the turn is given by r. The time the car takes to go around the turn is t. There is friction f between the tires and the road. The car makes the turn at high speed without doing into a skid (slide). After the turn the car continues down the road at constant speed. (A) Draw a free-body diagram which shows the forces acting on the car and the radius of the curve. Assume rolling friction and air drag are negligible (and that no propulsion force is required to maintain a constant speed). Include your coordinate axes. (B) Use Newton's second law to write an equation for the resulting centripetal force. Solve this equation for centripetal force in terms of: the mass of the car m, the radius of the curve r, time to make the curve t, and any needed constants of proportionality. Simplify as possible. (C) If the car makes the turn in 3.80 seconds and the right hand turn in the road has a radius of 45.7m, would a coefficient of static friction between the tires and the road is 0.90 be sufficient to keep the car on the road?
