Physics
You swing a bat and hit a heavy box with a force of 1273 N. The force the box exerts on the bat is Group of answer choices less than 1273 N if the box moves. exactly 1273 N whether or not the box moves. None of the above choices are correct. exactly 1273 N only if the box does not move. greater than 1273 N if the bat bounces back. greater than 1273 N if the box moves.

Ответ:
exactly 1273 N whether or not the box moves.
Explanation:
In the case when the bat is swing and it is hitted to a heavy box having a force of 1273 N so here the force of the box that exert on the box should be accurately 1273 N even if the box is moved or not. As the third law of the newton should be equivalent & the opposite reaction
Therefore as per the given situation, the above represent the answer
Ответ:
acting on it is
Force = (mass) x (centripetal acceleration)
= (mass) x (speed² / radius of the circle) .
So Force = (3 kg) x (3 m/s)² / (2 m)
= (3 kg) x (9 m²/s²) / (2 m)
= (27 kg-m²/s²) / (2 m)
= 13.5 kg-m/s² = 13.5 Newtons
