A race car on Bonneville flats is operated by a jet engine. The jet fuel isconsumed at a rate of k = 8.76 moving at a constant speed of 298.54relative to the car. The car experiences a resistance of 2kv, where v isthe speed of the car. The initial weight of the car is half car and halffuel. What is the speed of the car at the instant it runs out of fuel?

Step 1:To solve this problem, we'll use Newton's second law of motion, which states that the net…

1 kg of benzene is poured into a flask and heated to 353 K (the boiling point of benzeneat 1 atm.) using a heating element that has a power of 700 W (we ignore thatit's probably not so healthy and smart to do).

6. As shown in Figure, a gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes in series: Process 1-2: Compression with U 2 =U 1 . Process 2-3: Constant-volume cooling to p 3 =140 kPa,; V 3 =0.028 m^ 2 . Process 3 - 1 : Constant-pressure expansion with W 31 =10.5 kJ. For the cycle, W eycle =28.3 kJ . There are no changes in kinetic or potential energy. Determine (a) the volume at state 1, in m ^ 3 . (b) the work and heat transfer for process 1-2, each in kJ. (e) Can this be a power cycle? A refrigeration cycle? Explain.
