Respuesta :
Acceleration is non zero but the velocity is zero.
Answer: Option 2.
Explanation:
Acceleration is the speed that an object gains with in a short period of time. In the language of Mechanics, Acceleration is the change in the velocities of the objects with respect to the time. So when a ball is thrown up in the air, there will be some acceleration and there will be some speed that the ball will gain when thrown up.
Velocity is the speed of an object but in a particular direction. Velocity of an object is the rate of change of the position of the object with respect to the frame of reference of that frame. So the velocity of the ball up in the air is zero.
The statement that best describes the balls velocity and its acceleration after it is thrown up is that Velocity is zero and acceleration is nonzero.
Acceleration of an object can be defined as the speed with which it moves. It is the speed gained with respect to time.
It can also be defined as a change in velocity of an object.
When the ball goes up, it would be accelerating. This tells us that the acceleration is non zero.
Velocity is the rate at which there is change in a position. Due to the frame of the ball, the velocity is going to be zero.
