Answer:
angular moment is 0.25 kg.m²/s
Step-by-step explanation:
given data in question
mass (m) = 0.25 kg
length of string i.e. radius (r) = 0.5 m
velocity = 2 m/s
to find out
angular momentum before mass release
solution
we know angular moment formula i.e.
angular moment = mass × velocity × radius ................1
put the value mass velocity and radius in equation 1 we get angular moment i.e.
angular moment = mass × velocity × radius
angular moment = 0.25 × 2 × 0.5
angular moment = 0.25
so the angular moment is 0.25 kg.m²/s before release and 0.25 kg.m²/s after release because angular momentum is always conserved
