Explanation:
Complete Question
player passes a 0.6 kg basketball downcourt for a fast break. The ball leaves the player's hands with a speed of 9 m/s and slows down to 5.4 m/s at its highest point.
a.) How high (above the release point) is the ball when it is at its maximum height
b) How would doubling the ball's mass affect the result in part (a)?
Answer:
a The maximum height is 
b The mass would not effect the height because by making s the subject in the equation of motion

We see that it is not dependent on mass
Explanation:
From the question we are told that
The mass of the baseball is 
The speed it leave hands is 
The speed it slow down to is 
According to the law of motion

Now a is the acceleration and in this question is the acceleration due to gravity denoted as
the negative sign shows that it is moving against gravitational force
Substituting this into the equation

Substituting values and solving for s we have
