Question

mm.
A ball is dropped from a height h1= 1200 mm. If the coefficient of restitution is 80, the height of 5threbound from a horizontal floor is h5=​

Answer 1

6667=-80-9

Step-by-step explanation:

Answer 2

Concept Introduction:

When a ball is dropped from a height on the ground then the hight of its rebound gets reduced in its second time then the hight will deacrease continously till the ball gets stopped.

Given:

• A ball is dropped from a height $h1=1200mm$.
• The coefficient of restitution is $80$.

To find:

What will be the height of $5$th rebound from the horizontal floor.

Solution:

According to the problem,

We know that the height to which the ball goes up after it rebounds for the $n$th time is $he^{2n}$.

So, the height of $5$th rebound from the horizontal floor will be$he^{2n}\\ =(1200*80^{2*5} )mm$

So, the answer is $(1200*80^{2*5})mm$
