A tennis ball is thrown from a 25 m tall building with a zero initial velocity. At the same moment, another ball is thrown from

Nataly [62]

Answer:

The two balls meet in 1.47 sec.

Explanation:

Given that,

Height = 25 m

Initial velocity of ball= 0

Initial velocity of another ball = 17 m/s

We need to calculate the ball

Using equation of motion

$s=ut+\dfrac{1}{2}gt^2+h$

Where, u = initial velocity

h = height

g = acceleration due to gravity

Put the value in the equation

For first ball

$s_{1}=0-\dfrac{1}{2}gt^2+25$ ....(I)

For second ball

$s_{2}=17t-\dfrac{1}{2}gt^2+0$ ....(II)

From equation (I) and (II)

$-\dfrac{1}{2}gt^2+25=17t-\dfrac{1}{2}gt^2+0$

$t=\dfrac{25}{17}$

$t=1.47\ sec$

Hence, The two balls meet in 1.47 sec.
