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 $s =2.64m$

b The mass would not effect the height because by making s the subject in the equation of motion

$s = \frac{v^2 -u^2}{2g}$

We see that it is not dependent on mass

Explanation:

From the question we are told that

The mass of the baseball is $m_b = 0.6kg$

The speed it leave hands is $v_h = 9m/s$

The speed it slow down to is $v_s = 5.4m/s$

According to the law of motion

$v_s^2 = v_h^2 + 2as$

Now a is the acceleration and in this question is the acceleration due to gravity denoted as $-g$ the negative sign shows that it is moving against gravitational force
