Answer:
0.79 s
Explanation:
The initial velocity of the ball is, [tex]u=7.79 m/s[/tex].
And now we know that first equation of motion.
[tex]v=u+at[/tex]
Here, v is the final velocity, u is the initial velocity, t is time taken by the object, a is the acceleration.
Given that, final velocity is zero and ball is inb upward direction means opposite to acceleration due to gravity which means a=-g. and the value of g is [tex]9.8 m/s^{2}[/tex]
Therefore,
[tex]0=u-gt\\t=\frac{u}{g}\\ t=\frac{7.79}{9.8}\\ 0.79 s[/tex]
Therefore, it is the required minimum time that player must waiot to touch the ball.
