Question

Q: Which direction are the force vectors pointing for a bullet fired from a gun. Assume that the bullet is traveling to the right at 750 m/s. (the bullets vector)
A: Up, Down, Left

B: Right, Up

C: Right, Down, Left

D: Left, Down


Hope someone sees this ♡ please?

Answer 1

Answer:

D: Left, Down

Explanation:

Assuming that the bullet has already left the gun, there are only two forces acting on the bullet now, during its motion:

- The force of gravity (the weight of the object), acting downward

- The air resistance acting against the direction of motion (so, if the bullet is moving right, the air resistance acts to the left)

As a result of these two forces:

- The bullet will accelerates downward in the vertical direction, due to the force of gravity

- The bullet will decelerated (slow down) along the horizontal direction, due to the air resistance that acts against the direction of motion of the bullet

So, the bullet will acquire a parabolic path.

Therefore, the correct answer is

D: Left, Down

Answer 2

Answer:

The correct answer is D.

Explanation:

The force vectors for a bullet fired from a pistol, which moves to the right at 750 m/s are directed to the left and down. This happens because the forces acting on it are gravity and air resistance, the force of gravity has a downward direction and the force of air resistance has a leftward direction, contrary to the direction of the bullet.

Have a nice day!
