Want this question answered?
whenever an object is thrown in the air we must know the initial velocity with which the object has been thrown.
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
yes it does, however, the velocity at which the object is thrown also is a factor to consider.
If it is thrown at an angle, at the top of its path, its vertical velocity will be zero, however its horizontal velocity will be the same as its initial horizontal velocity minus whatever loss in speed as a result of air friction at that point. We won't know what that is without more information.
Mark off the x-axis in seconds. Mark off the y-axis in meters per second. The graph is a straight line, starting at the origin, sloping down with a slope of -9.8 meters per second per second. It never gets above the x-axis, and 'y' is negative everywhere on the graph. That's because the velocity is always negative (speed directed downward).
9.8
16 feet/second is the speed. To know the velocity, you would also need to specify the direction in which the object moves.
It depends on the height of the building and also on the direction the object is thrown in (up, down etc.).

Yes. An example of this would be a ball thrown straight up; at the very peak of its travel, it's not moving either up or down and therefore has an instantaneous velocity of zero.
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
yes it does, however, the velocity at which the object is thrown also is a factor to consider.
An object would need to start at about 25 miles per second in order to escape Earth's gravity.
If it is thrown at an angle, at the top of its path, its vertical velocity will be zero, however its horizontal velocity will be the same as its initial horizontal velocity minus whatever loss in speed as a result of air friction at that point. We won't know what that is without more information.

depends on the angle with which it is thrown, the velocity given to it.
When an object falls vertically downward, its velocity increases according to the following equation:2aS=vf2 - vi2 or ,2*10*S=v2, orv=(20S)1/2.There is a second case in which a body is thrown vertically upward, here its velocity decreases as it moves upward. Here its velocity becomes zero as it reaches the highest point
