Your pet hamster sits on a record player whose angular speed is constant. if he moves to a point twice as far from the center, then his linear speed

doubles

halves

remains the same

doubles

Explanation:

The relationship between angular speed and linear speed in case of a circular motion is the following:

where

v is the linear speed

is the angular speed

r is the distance from the centre of the circular path

In this proble, the pet hamster moves to a point twice as far from the center; this means that its distance from the centre, r', is doubled:

While the angular speed remains the same. Therefore, the new linear speed is

So, the correct answer is

the linear speed doubles

not really sure but thinking 1.54 mm/us
