Question

A 1.8 kg object is whirled on the end of a string that is 1.6 m long at a speed of 12.3 m/s. Calculate the angular momentum of the

object.
(Round your response to the nearest tenth, if necessary, and include the base unit abbreviation with your answer.)

Answer 1

35.42kg m^2 s−1

Step-by-step explanation:

Step one:

the expression for angular momentum is given as

`L = mvr`

m = mass = 1.8kg

v = velocity = 12.3m/s

r = radius= 1.6m,

Required

L = angular momentum

Step two:

substitute into the expression

L=1.8*12.3*1.6

L=35.42kg m^2 s−1
