A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 30 m. If he completes the 200 m dash in 23.2 s and runs at constant speed throughout the race, what is the magnitude of his centripetal acceleration as he runs the curved portion of the track?
As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm, which then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 3.00g while in circular motion with radius 9.45 m.
Using the average distance of Earth from the Sun, and the orbital peirod of Earth, (a) find the centripetal acceleration of Earth in its motion about the Sun. (b) Compare this value to that of the centripetal acceleration at the equator due to Earth’s rotation.
A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has an 8.00-m radius, at how many revolutions per minute are the riders subjected to a centripetal acceleration equal to that of gravity?
An athlete swings a ball, connected to the end of a chain, in a horizontal circle. The athlete is able to rotate the ball at the rate of 7.84 rev/s when the length of the chain is 0.600 m. When he increases the length to 0.900 m, he is able to rotate the ball only 6.23 rev/s. (a) Which rate of rotation gives the greater speed for the ball? 6.23 rev/s? 7.84 rev/s? (b) What is the centripetal acceleration of the ball at 7.84 rev/s? ___m/s2 (c) What is the centripetal acceleration at 6.23 rev/s? ____m/s2
The earth has a radius of 6380 km and turns around once on its axis in 24 hours. (a) What is the centripetal acceleration of an object at the earth's equator? Give your answer in m/s and as a fraction of g. (b) If the centripetal acceleration of at the equator is greater than g, objects would fly off the earth's surface and into space. What would the period of the earth's rotation to start this fly off?
The earth has a radius of 6380 km and turns around once on its axis in 24 h. (a) What is the radial acceleration of an object at the earth’s equator? Give your answer in and as a fraction of g. (b) If at the equator is greater than g, objects will fly off the earth’s surface and into space. What would the period of the earth’s rotation have to be for this to occur?
An astronaut is being tested in a centrifuge. The centrifuge has a radius of 2 m and, in starting, rotates according to θ = 6t^2, where t is in seconds and θ is in radians. When t = 5 s, what are the magnitudes of the astronaut’s (a) tangential acceleration, and (b) radial acceleration?
An object moving in a circular trajectory experiences both centripetal and tangential accelerations. Can the two accelerations ever cancel each other out? a No. b You're kidding, right? c Yes. d Only if the plane of the trajectory makes an angle with the vertical.
An aircraft performs a maneuver called an "aileron". During this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. It takes it 6.4s to complete the circle and the wingspan of the plane is 9.3m. What is the centripetal acceleration of the wing tip?
A runner taking part in the 200 m dash must run around the end of a track that has a circular arc with a radius of curvature of 35 m. The runner starts the race at a constant speed. If she completes the 200 m dash in 22.6 s and runs at constant speed throughout the race, what is the magnitude of her centripetal acceleration (in m/s2) as she runs the curved portion of the track?
At the northern tropic which you may take to be at 19 degrees north, air rises directly upwards from the surface of the Earth due to thermal forces at a speed of 45 m/s. What is the magnitude of the Coriolis and Centrifugal acceleration felt by the rising air due to the rotation of the Earth?
