Do you mean "What effect does friction have on the velocity of the ball?"
The critical velocity of a ball moving in a vertical circle is the minimum velocity required at the top of the circle to prevent the ball from losing contact with the track. Below the critical velocity, the ball will fall off the track at the top of the circle.
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
The ball's velocity changes to 0m/s and the boy's stays the same.
The horizontal distance traveled by the ball can increase by increasing the initial velocity of the ball or by reducing the effect of air resistance. Additionally, increasing the launch angle of the ball can also help it travel further horizontally.
The velocity of the ball is 16 feet/sec when it is thrown upward.
The ball returns to the ground with increasing velocity due to acceleration due to gravity. At a point (terminal velocity) the ball maintains a constant velocity (due to air resistance) This occurs when the weight of the ball is equal to the viscous drag of the air (air resistance) and upthrust (weight of air displaced).

You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
The horizontal component of the initial velocity of the ball is the velocity in the horizontal direction at the moment the ball is launched. It represents the speed and direction at which the ball is moving side-to-side.
The ball's velocity changes to 0m/s and the boy's stays the same.

The horizontal distance traveled by the ball can increase by increasing the initial velocity of the ball or by reducing the effect of air resistance. Additionally, increasing the launch angle of the ball can also help it travel further horizontally.
The velocity of the ball is 16 feet/sec when it is thrown upward.
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
The acceleration of the ball is constant during any time interval where the velocity changes. At the moment the ball has zero velocity, the acceleration is the same as it was during the time interval when the velocity was changing. This can be calculated using the formula acceleration = change in velocity / change in time.
The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
