Concept explainers
A typical laboratory centrifuge rotates at 4000 rpm. Test tubes have to be placed into a centrifuge very carefully because of the very large accelerations.
a. What is the acceleration at the end of a test tube that is 10 cm from the axis of rotation?
b. For comparison, what is the magnitude of the acceleration a test tube would experience if stopped in a 1.0-ms-long encounter with a hard floor after falling from a height of 1.0 m?

- A jet fighter pilot knows he is able to withstand an acceleration of 9g before blacking out. The pilot points his plane vertically down while traveling at Mach 3 speed and intends to pull up in a circular maneuver before crashing into the ground. (a) Where does the maximum acceleration occur in the maneuver? (b) What is the minimum radius the pilot can take?arrow_forwardA car initially traveling eastward turns north by traveling in a circular path at uniform speed as shown in Figure P7.15. The length of the arc ABC is 235 m, and the car completes the turn in 36.0 s. (a) Determine the cars speed. (b) What is the magnitude and direction of the acceleration when the car is at point B?

Drivers are cautioned to slow down to 40 mph as they navigate the curve.a. If you heed the sign and slow to 40 mph, what will be your acceleration going around the curve at this constant speed? Give your answer in m/s2 and in units of g.b. At what speed would your acceleration be double that at the recommended speed?arrow_forward
- Helicopter blades withstand tremendous stresses. In addition to supporting the weight of a helicopter, they are spun at rapid rates and experience large centripetal accelerations, especially at the tip. A. Calculate the magnitude (in m/s2) of the centripetal acceleration at the tip of a 3.40 m long helicopter blade that rotates at 240 rev/min. B. Compare the linear speed of the tip with the speed of sound (taken to be 340 m/s). Vtip/VSound =arrow_forwardWhile at the county fair, you decide to ride the Ferris wheel. Having eaten too many candy apples and elephant ears, you find the motion somewhat unpleasant. To take your mind off your stomach, you wonder about the motion of the ride. You estimate the radius of the big wheel to be 15 m, and you use your watch to find that each loop around takes 25 s.a. What are your speed and magnitude of your acceleration?b. What is the ratio of your apparent weight to your true weight at the top of the ride?c. What is the ratio of your apparent weight to your true weight at the bottom?arrow_forwardA race car moves on a circular track at a uniform speed of 30.0 m/s in a counterclockwise direction. The radius of the track is 75.0 m. What is the direction of the car’s acceleration? b. What is the magnitude of the car’s acceleration?arrow_forward
- A Ferris wheel with radius R = 15.0 m is turning about a horizontal axis through its center. The linear speed of a passenger on the rim is constant and equal to 7.40 m/s. a. What is the magnitude of the passenger's acceleration as she passes through the lowest point in her circular motion? b.arrow_forwardAn object moves in a horizontal circle at constant speed v (in units of m/s). It takes the object T seconds to complete one revolution. a. Derive an expression that gives the radial acceleration of the ball in terms of v and T, but not r. b. If the speed doubles, by what factor must the period T change if arad is to remain unchanged? c. If the radius doubles, by what factor must the period change to keep arad the same?arrow_forwardOn an otherwise straight stretch of road near Netherland, Colorado, the suddenly turns. This bend in the road is a segment of a circle of radius 110m. Drivers are cautioned to slow down to 75km/h as they navigate the curve. A. Draw a useful picture for this situation, indicating directions of the acceleration and velocity as the car goes around the curve. B. If you heed the sign and slow to this speed as you go around the curve, what will be your acceleration? C. At what speed will your acceleration be double that of part B?arrow_forward
