Question

A ball is thrown vertical with a velocity of 20 metre per second after 5 second its velocity be become zero, calculate the maximum height attend by the ball​

Answer 1

Answer :-

• Maximum height attained by the ball = 20 meters.

Given :-

• A ball is thrown vertical with a velocity of 20 metre per second after 5 second its velocity becomes zero.

To Find :-

• Maximum height attained by the ball.

Step By Step Explanation :-

It is given that a ball is thrown vertical with a velocity of 20 metre per second after 5 second its velocity be become zero.

We need to calculate the maximum height attained by the ball.

Let's do it !!

Using third equation ⤵

v² - u² = 2gh

By substituting the values ⤵

$\implies \sf{0}^{2} - {(20)}^{2} = 2 \times ( - 10) \times h \\ \\ \implies \sf - 400 = - 20h \\ \\ \implies\sf\cancel\cfrac{ - 400}{ - 20} = h \\ \\ \implies \bf20\:meters = h$

Therefore the maximum height attained by the ball = 20 meters.
