## Cyclist

A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. After 14.0 s, the wheels have made 112 rev.

What is the angular acceleration of the wheels?

What is the angular acceleration of the wheels?

**7.18 rad/s^2**

What is the angular velocity of the wheels after 14.0 s?**1.01×102 rad/s**If the radius of the wheel is 31.0 cm, and the wheel rolls without slipping, how far has the cyclist traveled in 14.0 s?**2.18×102 m**## Discussion

can someone please let me know which ones i got wrong. i

cant seem to figure this one out. thanx

For a given time, mass 2 travels a distance LESS THAN mass 1.

The tangential acceleration of mass 1 GREATER THAN the tangential acceleration of mass 2.

For a given time, the angle covered by mass 2 is EQUAL TO mass 1.

The moment of inertia of mass 2 is LESS THAN the moment of

inertia of mass 1. (Both moments of inertia are taken about the axis of rotation.)

The radial acceleration of mass 1 LESS THAN the radial acceleration of mass 2.

The speed of mass 1 is EQUAL TO mass 2.

Greater Than: The radial acceleration of mass 1 ____ the radial acceleration of mass 2.

Greater Than: The speed of mass 1 is ____ mass 2.

Greater Than: For a given time, mass 1 travels a distance ____ mass 2.

Equal To: For a given time, the angle covered by mass 2 is ____ mass 1.

Equal To: The tangential acceleration of mass 1 ____ the tangential acceleration of mass 2. Greater Than: The moment of inertia of mass 1 is ___ the moment of inertia of mass 2. (Both moments of inertia are

taken about the axis of rotation.)
