Thank you Question 2 (5 marks) A new sports car has a drag coefficient of 0.32 and a frontal area of 1.60 m² and is travelling at 140 km/h. How much power is required to overcome aerodynamic resistance if p 1.23 kg/m3? (1 decimal place) -
The drag coefficient of a sports car is 0.58 and its frontal area is 1.3m2. Although the engine output is rated at 420HP, how much power is required to cruise at 80mph?
For a touring bicyclist the drag coefficient C (wherefair=12CAρv2) is 1.06, the frontal area A is 0.460 m2 , the air density ρ is 1.20 kg/m3 ,and the coefficient of rolling friction is 4.10×10−3. The rider has mass 53.0 kg , and her bike has mass 12.4 kg . Part A To maintain a speed of 12.3 m/s on a level road, what must the rider's power output to the rear wheel be? P = W Part B For racing,...
The drag coefficient of a car is to be determined experimentally with a full scaleWind tunnel test in a large wind tunnel. The wind speed is60 mih 00 km/h (60 mi/h) and the drag force measured on a scale as shown in the adjacent drawing is 302 N (68 lbf). The frontal area of the car is 2.068 m2 (22.26 ft2) Neglect any ground effect due to the floor not moving relative to the car (a) Calculate the drag coefficient...
2. The electric vehicle Tesla Model S has a drag coefficient of 0.24, a mass of 2100 kg, and a frontal area of 2.4 m2. The coefficient of rolling resistance of its tires is 0.01. Recall the density of air at sea level is 1.3 kg/m3. How much kinetic energy is required to overcome rolling resistance and air resistance (drag) at Autobahn speeds of 180 km/hr for a 200 km trip? How much useful energy (in MJ) and money (in...
The answer is given as V = 60.3 mph, but no solution is provided The aerodynamic drag on a car depends on the shape of the car. For example, the car shown in Fig. 3 has a drag coefficient of 0.36 with the windows and roof closed. With the windows and roof open, the drag coefficient increases to 045. With the windows and roof open, at what speed is the amount of power needed to overcome aerodynamic drag the same...
A Toyota Prius has the following attributes: Drag Coefficient Ca = 0.24, Frontal Area Af = 25.83 ft?, weight = 3064 lb, and Speed = 90 mph. Use air density p = 0.002378 slugs/ft3. The vehicle from problem 2 above is travelling down a 4% grade on pavement located at 5000-ft altitude (p = 0.002045 slugs/ft?) with its maximum speed. Overall resistance for the motion of the car at maximum speed is overcome with a power of 28hp. Determine the...
A box with a frontal area of 2.0 feet-squared and with a drag coefficient of C-sub-D = 0.9 is fastened to the roof of your car. What is the aerodynamic drag force in pounds due to the box alone at a velocity of 88 feet-per-second? Enter the answer in pounds
please show work A 3200 lb vehicle is being designed with a drag coefficient of 0.35 and a frontal area of 50 ft2, If the vehicle is traveling at 70 miles per hour on a downhill grade of 2 % at an air density of 0.002378 slugs/ft3, what tractive effort is required to overcome the vehicle resistance forces (in Ib)?| A 3200 lb vehicle is being designed with a drag coefficient of 0.35 and a frontal area of 50 ft2,...
(25pts) A car has a drag coefficient of CD=0.3 The area of the car is 24ft2. The weight of the car is 3000lbf. The car is travelling at V=75mph through air at sea level (ρ=0.0024 slug/ft3). Treat the rolling friction as μ=0.015. Model the power needed to move the car per the lecture as: . Watch your units. What is the power needed to travel at 75mph, in units of horsepower (hp)? How long does it take to travel one...
