circular path of radius 5.0 m at a uniform speed of 10. m/s. What is the magnitude of the object's centripetal
acceleration ? 10.0 m/s2 2.0 m/s2 5.0 m/s2 20. m/s2
1. An object travels in a
circular path of radius 5.0 m at a uniform speed of 10. m/s. What is the magnitude of
the object's centripetal
acceleration ?
10.0 m/s2 2.0 m/s2 5.0 m/s2 20. m/s2
2. While an object is
undergoing uniform circular motion, its acceleration is directed
toward the center of the circle away from the center of the circle tangent to the circle
3. An astronaut is standing
inside a rotating space station against the outer wall. If the speed of rotation
of the space station were
doubled, the centripetal acceleration of the astronaut would
decrease increase remain the same
4. A 3.0 kg mass is traveling
in a circle of 0.20 m radius with a centripetal acceleration of 20. m/s2.
What is the speed of the mass ?
1.0 m/s 2.0 m/s 10. m/s 20. m/s
5. An
object moves around a circle whose radius is 2.0 m. The constant speed of the object is
6.0 m/s. What is the centripetal
acceleration of the object ?
12 m/s2 18 m/s2 3.0 m/s2 0.33 m/s2
