Texas Motor Speedway On October 28, 2000 Gil de Ferran set the single-lap average speed record for the then-named California Speedway—241.428 mi /h. The following year, on April 29, 2001, the Championship Auto Racing Teams (CART) organization canceled the inaugural Firestone Firehawk 600 race at the Texas Motor Speedway 2 hours before it was to start. During practice, drivers became dizzy when they reached speeds of more than 230 mph on the high-banked track. The Texas Motor Speedway has turns banked at
What was the approximate radius of the part of the track where the drivers experienced the 5.5g acceleration?
75 For the racecars to stay on the road while traveling at high speed, how does a friction force need to be exerted?
a. Parallel to the roadway and outward
b. Parallel to the roadway and toward the infield
c. Horizontally toward the center of the track d. Opposite the direction of motion
e. None of the above

- An aircraft performs a maneuver called an "aileron roll." During this maneuver, the plane turns likea screw as it maintains a straight flight path, which sets the wings in circular motion. If it takes it 35s to complete the circle and the wingspan of the plane is 11 m, what is the acceleration of the wingtip?A) 5.6 m/s2 B) 1.0 m/s2 C) 0.99 m/s2 D) 0.18 m/s2arrow_forwardA race car with a mass of 750kg is traveling at a constant speed of 75m/s around a circular track of an radius of 50m. A-what is the direction and the magnitude of the centripetal acceleration of the racecar? B- what happens to the centripetal force of the car if the speed is doubled?arrow_forwardA car with a constant speed of 95 km/h enters a circular flat curve with a radius of 0.5 km. The friction between the road and the car's tire can supply a centripetal acceleration of 1.35 m/s². What is the acceleration the car need to remain in this curve regardless of its acceleration of 1.35 m/s²? a) 2.39 m/s² b) 1.74 m/s² c) 1.35 m/s² d) 1.39 m/s² V₁ = V + at лd²h V= C=d F = ma ac r x=x+(+v₁)t +mgh+Fyud F rarrow_forward

- A skater is trying to perform a Triple revolution jump. His vertical take off speed is 2.8 m/s. How fast does he need to rotate to complete the triple revolution in the air? (in rotation per second) Assuming g=9.8 m/s² Your Answer: Answerarrow_forwardCIRCULAR MOTION 1. A centrifuge spins a suspension at 2500 rpm (revolutions per minute) in a radius of 20 cm. What is the acceleration of the suspension? 2. When you take your 1200-kg car out for a spin, you go around a corner of radius 57 m with a speed of 15 m/s. Assuming your car doesn't skid, what is the force exerted on it by static friction? 4740 N (my teacher's answer)arrow_forwardA 50 Gram sample of Uranium ore is put into a centrifuge that runs at 30,000 rpm.

(a) How long would it take for an object to fall from rest a vertical distance of 1.00 m? (b) What is the escape velocity from a very small planet? (c) Suppose the Little Prince throws a ball vertically upward, giving it an initial velocity of 1.0 m/s. What would be the maximum height reached by the ball? (d) At what speed could a ball be thrown horizontally so that it would travel in a circular orbit just above the surface of the planet?arrow_forward8. How is it possible that a body moves at a constant speed and is still in accelerating motion? 9. When a car is going around a circular track with constant speed, what provides the centripetal force necessary for circular motion?arrow_forwardAn ultracentrifuge accelerates uniformly from rest to 100,000 rpm in 2.0 min. If this ultracentrifuge accelerates 4.0 seconds starting from rest, what is the magnitude of the centripetal acceleration in unit of gravitational acceleration g for your sample sitting at 4.0 cm from the center axis? Use g = 9.8 m/s2. Hint: compute the centripetal acceleration in unit of m/s2 first, then divided by g will be your answer. For example, if your centripetal acceleration is 19.6 m/s2, your answer measured in unit of g is 2.0.arrow_forward
