This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A curve in a speed track has a radius of 1200 ft and a rated speed of 120 mi/h. A racing car starts skidding on the curve when traveling at a speed of 180 mi/h. Determine: a. the banking angle θ
b. the coefficient of static friction between the tires and the track under the prevailing conditions
c. the minimum speed at which the same car could negotiate the curve.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
