Answer:
a. L =3.465 J.s
b. 3.186 rad/s
c. T = 1.972 s
d. Lp = 0.022 J.s; up or down, depending on the direction of L
Explanation:
(a)We have the formula for angular momentum as
L = I*w where I = moment of inertia =
L =
(b) ω = M*g*D/L
where D = L/2 = 0.96/2 = 0.48m
ω = (23* 0.48/3.465) rad/s = 3.186 rad/s
(c) T = 2π/ω
T = 2*π/3.186 s = 1.972 s
(d) Lp =
Solving with mass M, D and angular velocity ω
Lp = 0.022 J.s; up or down, depending on the direction of L
