Question

Please help!!!!

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

Answer 1

Answer:option C

Step-by-step 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
