At the beginning of a basketball game, a referee tosses the ball straight up with a speed of 4.41 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?

To develop this problem we will apply the linear motion kinematic equations. For this purpose we will define the change in speed as the product between acceleration and time.

The relation between initial velocity final velocity and time is

The acceleration is due to the acceleration due to gravity, then we have

At the maximum height the final velocity is zero. Then we have that

The time the player must wait before touching he ball is

it breaks and dirupture other materials and other sencews from the bottom

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
