At the beginning of a basketball game, a referee tosses the ball straight up with a speed of 7.79 m/s. a player cannot touch the ball until after it reaches its maximum height and begins to fall down. what is the minimum time that a player must wait before touching the ball?

0.79 s

Explanation:

The initial velocity of the ball is, .

And now we know that first equation of motion.

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

Therefore,

Therefore, it is the required minimum time that player must waiot to touch the ball.

i think it's 35 meters
