Uniform circular motion introduction

Circular motion basics: Angular velocity, period, and frequency

A catapult of pole length 9, r throws a watermelon from one end of a pole which rotates about an axis at the other end with angular speed omega.

A smaller catapult of pole length r throws another watermelon from one end of a pole which rotates about an axis at the other end with the same angular speed omega as the first catapult.

How does the linear speed of the larger catapult's watermelon v, start subscript, start text, l, a, r, g, e, end text, end subscript compare with the smaller catapult's watermelon v, start subscript, start text, s, m, a, l, l, end text, end subscript?

Choose 1 answer:

(Choice A)
v, start subscript, start text, l, a, r, g, e, end text, end subscript, equals, v, start subscript, start text, s, m, a, l, l, end text, end subscript
(Choice B)
v, start subscript, start text, l, a, r, g, e, end text, end subscript, equals, 3, v, start subscript, start text, s, m, a, l, l, end text, end subscript
(Choice C)
v, start subscript, start text, l, a, r, g, e, end text, end subscript, equals, 9, v, start subscript, start text, s, m, a, l, l, end text, end subscript
(Choice D)
v, start subscript, start text, l, a, r, g, e, end text, end subscript, equals, start fraction, v, start subscript, start text, s, m, a, l, l, end text, end subscript, divided by, 9, end fraction
