So based on what I've understood I derived following equation:
Wnet = Wacc + Wcv
Where:
Wnet = Total work produced by the car. (36000 kJ)
Wacc = Work produced during acceleration.
Wcv = Work produced during constant velocity.
So for acceleration part:
Wacc = (Fapp - Ffric)d
Wacc =...
Regarding the work equation, I figure since car is accerating forward it's +ve and friction is preventing the car from accelerating; thus, -ve.
Isn't this right?
Homework Statement
Given that the car produced work (W) of 32000 kJ during the trip to move forward on a flat pavement with coefficient of friction of 0.2, how far did the car travel?
Assume that the car was at rest then it accelerates to 100 km/h in 12 s, and then which maintained constant...
Homework Statement
If there's a polytropic process (n = 1.51) compressor that compresses air (Ideal Gas) as:
In: 100 kPa @ 25c
Out: 30 MPa
Given Data: Mass (m) = 105 kg, Work done by compressor (W) = 160000 kJ
a. What is the exit temperature of the air from the compressor?
b. If an...
