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.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
