Question

A ball is allowed to fall freely from the top a of a tower to the ground level
c.B is the midpoint of ac.T1 and t2 are the times taken by the ball to cover the distances ab and bc. What is the value of t1/t2

Answer 1

Answer:

what is me cry of it did it cause what is the things but is it wrong or right

Answer 2

Answer:

The ratio of $t_{1}\ and\ t_{2}$ is $\sqrt{2}$.

Explanation:

Given is a ball that is allowed to fall freely from the top of the tower

(Point A) to the ground (Point C) where (Point B ) is the midpoint of AC.

Let the height of the tower be h,

So,

$\frac{h}{2} =\frac{1}{2} \times g\s\times t_{1} ^{2} \\t_{1} =\sqrt{\frac{h}{g} } \ seconds$

For the second half,

Velocity after first half,

$v=0+gt_{1}=gt_{1}$

For the second half of the fall,

$\frac{h}{2} =gt_{1} \times t_{2} +\frac{1}{2} \times g\times t_{2} ^{2}$

On solving,$t_{2}=\sqrt{\frac{2g}{h} }$

Hence, the ratio of $t_{1}\ and\ t_{2}$ is $\sqrt{2}$.
