hi,
i have 5 questions i need the
complete solutions with their final results. is there anyonecouldhelp
me, i would appreciate that.
1)
Consider a point on a bicycle wheel as the wheel turns about afixedaxis, neither speeding up nor slowing down. Compare thelinear andangular velocities of the point.
2)
A point on the rim of a 0.25-m-radius rotating wheel hasacentripetal acceleration of 4.0 m/s2. What is the angular speedofthe wheel?
3)
A point on the rim of a 0.15-m-radius rotating disk hasacentripetal acceleration of 5.0 m/s2. What is the angular speedofa point 0.075 m from the center of the disk?
4)
A 0.150-m-radius grinding wheel, starting at rest, developsanangular speed of 12.0 rad/s in a time interval of 4.00 s. Whatisthe centripetal acceleration of a point 0.100 m from thecenterwhen the wheel is moving at an angular speed of 12.0rad/s?
5)
What centripetal force does an 80-kg passenger experiencewhenseated 12 m from the center of a Ferris wheel whose angularspeedis 0.50 rad/s?
thank you in advance
