Answer:
432 J
Explanation:
When moving linearly:
Kinetic Energy = (1/2)mV^2
So here you have:
KE=(1/2)(6)(12^2)=(1/2)(6)(144)=432
The unit for energy is Joules (J), so your answer would be 432 J.
Answer:
ωf = 4.53 rad/s
Explanation:
By conservation of the angular momentum:
Ib*ωb = (Ib + Ic)*ωf
Where
Ib is the inertia of the ball
ωb is the initial angular velocity of the ball
Ic is the inertia of the catcher
ωf is the final angular velocity of the system
We need to calculate first Ib, Ic, ωb:
ωb = Vb / (L/2) = 16 / (1.2/2) = 26.67 m/s
Now, ωf will be:
This study was aimed at testing the construct validity of the basketball basic motion skills test instrument (ITK GDBB). The research used descriptive method of 3 basketball experts in the city of Cimahi; 3 experts are the expert in basketball. The instrument used was the ITB GDBB developed by Silvy (2019) consisting of top passing, bottom passing, top service, bottom service, chest passing, bounding passing, overhead passing, and leading ball (dribbling). This instrument consists of 76 items that cover 4 domains in basketball, namely chest pass, overhead pass, bound pass, and dribbling. The validity method used the construct validity of different power types. For the reliability method, it used the Kuder Ricardson (KR) and Objectivity analysis. The results of the construct validity analysis of a total of 76 items show that the score is ranged from 0.67 to 1.00. The construct validity value of 71 items in the basketball game is in the high category (= 1.00), 5 items are in the sufficient category, the relativity score is ranged from 0.75 to 0.98, and the objectivity score is ranged from 0.89 to 0.95. The conclusion is that this test instrument can be used as a standardized basic motion skill test for standardized large ball games for validity in basic motion skills in basketball games for grade VII junior high school students.
En el presente ensayo se hace una reseña de las críticas que ha recibido la teoría de la ley natural, originalmente propuesta por Germain Grisez y posteriormente desarrollada por otros filósofos del derecho, como John Finnis, Joseph Boyle, William May y Patrick Lee. Los objetivos del autor son demostrar, en primer lugar, que contrariamente a lo que sus críticos afirman, la teoría de la ley natural propuesta por Grisez no excluye el supuesto de que el bien humano básico o las normas morales están basadas en la naturaleza humana o tienen conexión con ella; y en segundo lugar, que Grisez y sus seguidores están en lo correcto al mantener que nuestro conocimiento del bien humano básico y de las normas morales no necesita ni puede ser lógicamente deducido o inferido o derivado de los hechos de la naturaleza humana.
The answer is A. Cones, as rods are not sensitive to color. :)
