what is the angular momentum of a 1.25 kg mass rotating on the end of a string 1.0 m long at an angular speed of 180 radians/s?

a) 450 kg m2/s

b) 144 kg m2/s

c) 225 kg m2/s

option C

Explanation:

Angular momentum equal to radius times linear momentum

So ang momentum equal to

1 meter x (MV)

1 m x (1.25 kg x 180 m/s)

225 kg m square/second

Hence option C

the independent variable, or the one that is intentionally manipulated is the speed.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
