Answer: the speed at which it falls toward the Earth.
Explanation:
A bullet travelling across Earth's surface with some horizontal velocity is classical example of projectile motion.
Projectile motion is an idealization of the motion under the action of gravity neglecting the influence of the air (no drag force nor friction).
This kind of motion is the result of two independent motions: vertical motion and horizontal motion.
The observed net velocity is the vectorial sum of the vertical and horizontal velocities.
The horizontal velocity is constant, since there is not any force acting in the horizontal axis. Thi is, the object, following the first Law of Newton (inertia law) tends to continue in uniform rectilinear movement (with zero acceleration).
The vertical velocity, this is the velocity at which the bullet falls toward the Earth, is influenced (accelerated) by the action of the gravity of the Earth. So, the vertical velocity is accelerated by the pull of the Earth.
Vertical and horizontal velocities are independent of each other, which means that the speed or the magnitude of the horizontal velocity does not affect the speed at which an object (the bullet) falls toward the Earth.
Answer:
The correct option is B
Explanation:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion. A common physics demonstration relies on this principle that the more massive the object, the more that object resist changes in its state of motion.
Answer:
15x6=90 meters
Explanation:
i did 15x6 because it runs 15 meters per second
brainliest? >w<
Answer:
Friction = 5 N
Explanation:
As we know that block is moving at constant speed
So the acceleration of the block is zero
So we will have
for net force to be zero
Force exerted on the object by external system must be counter balanced by the force of friction
So we have
so we have
