Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
Answer:
In collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.
Explanation:
In a collision two objects, there is a force exerted on both objects that causes an acceleration of both objects. These forces that act on both objects are equal in magnitude and opposite in direction.
Thus, in collision between equal-mass objects, each object experiences the same acceleration, because of equal force exerted on both objects.

The only force acting on the ball, once it left the hand of the player, is the gravitational atraction of the earth. Once the ball reaches its maximum height, it starts a free fall movement under the action of earth's gravity.
Then the magnitude of the acceleration of the ball is the gravitational acceleration, g, approximatley 9.8 m/s^2
