73. We assume the given rate of 1.2

× 10

3

m/y is the linear speed of the top; it is also possible to interpret

it as just the horizontal component of the linear speed but the difference between these interpretations
is arguably negligible. Thus, Eq. 11-18 leads to

ω =

1.2

× 10

m/y

55 m

= 2.18

× 10

5

rad/y

which we convert (since there are about 3.16

× 10

7

s in a year) to ω = 6.9

× 10

13

rad/s.
