When we learn something new, then we know more stuff,
and that helps us avoid ignorance and superstition.
The REAL question is:

Answer:
L = 8694 Kg.m²/s
Explanation:
r = 270 ĵ m
v = 14 î m/s
m = 2.3 kg
θ = 90º
L = ?
We can apply the equation
L = m*v*r*Sin θ
L = (2.3 kg)*(14 m/s)*(270 m)*Sin 90º = 8694 Kg.m²/s
Yes that looks correct to me. good luck!!
