A car drives at 15 m/s and has an air resistance force of 210 N. What is the air resistance force at 30 m/s?
Homework Answers
as it act as viscous force = 6pi(n)rV
air resistance will double as it is propotional to velocilty,
air resistance will be = 420N
Add Answer to:

a 1800 kg car experiences a combined force of air resistance and friction that has the same magnitude whether the car goes up or down a hill at 24 m/s. going up a hill, the cars engine produces 44 hp more power to sustain the constant velocity than it does going down the same hill. At what angle is the hill inclined above the horizontal?

A 1500-kg car drives at 30 m/s around a flat circular track 300 m in diameter. What are the magnitude and direction of the net force on the car? Sort the following quantities as known, to find, or unneeded. Let m and v be the mass and speed of the car, respectively; μs is the coefficient of static friction, r is the radius of the circular path, n is the magnitude of the normal force acting on the car, and...

13) There are several types of drag on a car other than air resistance. Effects having to do with the squeezing of the tires (rolling resistance) and frictional forces in the drivetrain (the system that transfers energy from the engine to the rotation of the wheels) also must be taken into account. Engineers use the following equation to model the total force due to these different effects Fdrag=A+Bv+Cv2Fdrag=A+Bv+Cv2 For a Camry, these coefficients are estimated to be A=117.130A=117.130 N, B=1.800...

A 1500-\rm kg car drives at 30 \rm m/s around a flat circular track 300 \rm m in diameter. What are the magnitude and direction of the net force on the car? 9000N Since the net force is equivalent to the force of static friction, your answer to Part D is the magnitude f_s. Based on this value, what is the minimum coefficient mu_s of static friction between the road and the car?
