Question

A boy of 65 kg is skating around a circle with radius 3.8
meters. If he is moving at 4.25 m/s, what is his angular
momentum? (Round to the nearest hundredth).

A 1049.75 Nms
B 27.63 Nms
C 276.25 Nms
D 10.50 Nms
E 104.98 Nms

Answer 1

Answer:

A 1049.75

Explanation:

notice that a Nms is equal to a kg(m^2)/s which is what you get if multiply all three given values.

the formula is angular momentum = (mass)(velo)(radius)

therefore

65(3.8)(4.25) = the answer

= 1049.75
