Answer:

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.It applies to the cosmological and astrophysical realm, including astronomy.

The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves

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

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
