Question

Sapling Learning Rank the anguar speed of the folowing otojects, from highest to lowest: Abowling ball of radius 122 cm rotating at 342 radians per second. A tire of radius 0.501 m rotating at 35.4 rpm. A6.59 cm diameter top spinning at 145 degrees per second. A square, with sides 0625 mlong, whose comers are moving with tangentia speed1.75 mvs asit motates about its center. A rock on a string, being swung in adide of radius o 548 m with a oentripetal acceleration of 165 m/s2 Highest Angular Speed Top Bowling Ball Lowest Angular Speed Previous Gave up & view solution Check Answer ON rr SExi

Explanation / Answer

First: 3.42 radians/sec

Second: 35.4/60×2 = 3.67 r/s

Third : 145/360×2 = 2.53 r/s

For the fourth, the diagonal is 2s, and the circumference
swept by the corner is 2×.625m× = 2.7768m
1.78m /2.7768m × 2 = 4.028 r/s

For the fifth, centripetal acceleration = v²/r and v = (a×r)
(a×r) = (16.5m/s²×.548m)=(9.042m²/s²) 3m/s
Since circumference = 2r = 2×(.548m)× = 3.44m
at 3m/s the rock completes 3m/3.44m× 2 = 5.47r/s

So,
Rock >Square>Tire>Bowling Ball>Top
