Students in a lab measure the speed of a steel ball launched horizontally from a tabletop to be
The position at which a small piece of paper is placed so that a ball launched horizontally from a tabletop will hit it when it lands.
Answer to Problem 10TS
The piece of paper should be placed at a distance of 2 m from the table so that the ball will land on it.
Explanation of Solution
Given info: The horizontal velocity of the ball is
Write the expression for the horizontal distance from the table to the piece of paper.
Here,
Substitute
Conclusion:
Therefore, the piece of paper should be place at a distance of
