A large centrifuge, like the one shown in Figure 6.37(a), is used to expose aspiring astronauts to accelerations similar to those experienced in rocket launches and atmospheric reentries.
(a) At what
(b) The rider's cage hangs on a pivot at the end of the arm, allowing it to swing outward during rotation as shown in Figure 6.37(b). At what angle

- Circular orbits in Equation 13.10 for conic sections must have eccentricity zero. From this, and using Newton’s second law applied to centripeta acceleration, show that the value of in Equation 13.10 is given by Where is the angular momentum of the orbiting body. The value of is constant and given by this expression regardless of the type of orbit.arrow_forwardAn office door is given a sharp push and swings open against a pneumatic device that slows the door down and then reverses its motion. At the moment the door is open the widest, (a) does the doorknob have a centripetal acceleration? (b) Does it have a tangential acceleration?arrow_forwardA door in a hospital has a pneumatic closer that pulls the door shut such that the doorknob moves with constant speed over most of its path. In this part of its motion, (a) does the doorknob experience a centripetal acceleration? (b) Does it experience a tangential acceleration?arrow_forward
- Suppose a piece of dust has fallen on a CD. If the spin rate of the CD is 500 rpm, and the piece of dust is 4.3 cm from the center, what is the total distance traveled by the dust in 3 minutes? (Ignore accelerations due to getting the CD rotating.)arrow_forwardIs it possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration?arrow_forwardA good baseball pitcher can throw a baseball toward homeplate at 85 mi/h with a spin of 1800 rev/min. How many revolutionsdoes the baseball make on its way to home plate? For simplicity,assume that the 60 ft path is a straight line.arrow_forward
- Differ between the angular acceleration with the centripetal acceleration?arrow_forwardA point mass of .39kg is set to rotate about a fixed axis .76 m away. The mass is initially at rest and undergoes a constant angular acceleration of 5.10 rad/s^2. At what time will the centripetal force acting on the mass be 50.8N ?arrow_forwardA stone with a mass of 0.5 kg is tied to a string 1.2 m long and is whirled in a vertical circle. If the breaking strength of the string in tension is 20N, what is the angular velocity at which the cord will break?arrow_forward
- What would be the angular velocity of a centrifuge running at 2,000 rpm?arrow_forwarda stone tied to the end of a string 50cm long is whirled in a horizontal circle with constant speed . if the stone makes 20 revolutions in 40s , the angular velocity of the stone is?arrow_forwardHow fast (in rpm) must a centrifuge rotate if a particle 8.50 cm from the axis of rotation is to experience an acceleration of 120000 g's?arrow_forward
