A student spins a 15 g metal ball weight at the end of a 0.60 m string with a frequency of 3.0 revolutions per second. What is the angular momentum of the ball?

Question

anonymous · Answer

The angular momentum is given as I = mvr , where m is the mass of the ball, v is the tangential speed, and r is the radius of the rotation of the ball. The trick is how to find v? Well v is just distance over time. The distance covered is just 3 times the circumference of the circle per second. Hope that helps :)

Angular momentum L=mvr=m*omega*r^2=?

shamim · Answer

Given
m=15g=0.15kg
Omega=2*pi*f=?
f=3hz
r=0.6m
