Want this question answered?
The displacement, along the direction of measurement, is zero. It need not mean that the object is back at the starting point. The displacement-time graph, measuring the vertical displacement of a ball thrown at an angle, will have displacement = 0 when the ball returns to ground level but, unless you are extremely feeble, the ball will be some distance away, not at its starting point which is where you are. The use of such a graph is not unusual in the elementary projectile motion under gravity.
i dont knoe
baseball being thrown? soccer ball?
A Golf Ball
the angles that you hit the ball, how high you hit the ball, and the langth you hitt the ball. you also can find out how much force is on the ball:)
If you want the graph to show the acceleration of the ball against time, then the graph is a horizontal line. If you want the graph to show the velocity of the ball against time, then the graph is a straight line sloping downward. If you want the graph to show the height of the ball against time, then the graph is a parabola that opens downward.
If the graph is a straight line, then the slope of the line is the average acceleration of the ball.

In the traditional scoring system, a dot was used to indicate a ball whereby no run has been scored.

a ball rolled across a horizontal table moved at cont ant velocity why?
i dont knoe
This is because Titleist has agreements in place with PGATOUR.COM and The Golf channel that they will indicate which players use a Titleist ball.
The flags are used by the line judges to indicate various things which are under their responsibility. The most obvious is if the ball is either in or out when the ball has hit the court. Another use is hitting a foreign object in the playing area. This indicated by waving the flag backwards and forwards three times and pointing at the object. Another use is to indicate foot faults on the server or when someone is standing out of the court when the ball is hit at the serve. The final use is to indicate that the ball has hit either antennae, hit the tape below the antenna, hit the posts or the net outside the antenna or the ball passed outside the antenna and lands in court, in which case it is out.
