Question

A mass of 0.8kg at the end of a rope 0.5m long is whirled round in a horizontal circle at an angular speed of 10rad/s. Calculate the angular momentum of the whirled

Answer 1

Answer:

2 kgm/sec

Explanation:

given

mass= 0.8kg

radius of circular path = 0.5m

angular velocity (w)= 10 rad/sec

angular momentum = m(rw)r

= 0.8×(0.5×10)×0.5

= 2 kgm/sec
