If a metal ball, rubber ball and plastic ball is dropped from the same height, which ball will attain the greatest height after hitting an iron anvil. Why?
Answers
If we drop a metal ball and a plastic ball from the same height at the same time, then which ball will reach the ground first?
In this question the medium is not mentioned. Therefore i will consider both the cases i.e. in air as well as vacuum.
CASE 1
In air the metal ball will reach first as it is heavier in weight than a plastic ball and air resistance will have very less effect on it as compared to a plastic ball. The air resistance will slow down the plastic ball and may or may not change its path into a parabolic path due to movement of fast air around it. Well I will not discuss this now.
CASE 2
In vacuum there is no air to resist any of the ball and the time taken by any body does not depend upon its mass. Therefore the metal and the plastic ball will reach at the same moment.
Generally in thus question only 2nd case is considered unless mentioned. I just wrote case 1 for better understanding
I hope you will understand this.
