The answer is Stay In Place
Answer:
The ultimate determinant of truth in science is the execution of scientific experiments that prove or discredit a certain scientific statement. It was through scientific experiments that gravity was accepted scientifically.
Explanation:
Gravity was first observed by Isaac Newton, who quickly created theories and calculations to prove it and show that it exists, in addition to showing the influences it has on life and on the planet.
However its existence was discredited by several people, including men of science. Therefore, it was necessary to search for facts, calculations and evidence of its existence, so that it could be accepted and studied more and more deeply. The result of this, was the elaboration of diverse experiences that submitted the gravity to the most different tests until its existence was impossible to be denied.
Explanation:
Acceleration. Angular acceleration: Is the rate of change of the angular velocity of a body with respect to time.
Force. Torque: Is also called rotational force, since an applied torque will change the rotational motion of a body.
Mass. Moment of inertia: It is the resistance that opposes a body to rotates.
Work. Work: In a rotational motion, the work is done by the torque.
Translational kinetic energy. Rotational kinetic energy: is the kinetic energy due to the rotational motion of a body.
Linear momentum. Angular momentum: Represents the quantity of rotational motion of a body.
Impulse. Angular impulse: Is the change in angular momentum of a body.
Answer:
The value of impulse of the net force on the ball during its collision with wall is
The value of average horizontal force that the wall exerts on the ball during the impact is F = 15000 N
Explanation:
Mass of the ball = 0.5 kg
Horizontal velocity = 20
Velocity after collision = - 10
(A). Impulse of the net force on the ball during its collision with wall is
I = 0.5 × (20 + 10)
This is the value of impulse of the net force on the ball during its collision with wall.
(B). The magnitude of average horizontal force
Where F = Force
I = impulse & t = time interval = 0.001 sec
F = 15000 N
This is the value of average horizontal force that the wall exerts on the ball during the impact.
