At the start of a basketball game, the referee tosses a basketball straight into the air by giving it some initial speed. After being given that speed, the ball reaches a maximum height () above where is stated. Using the conservation of energy, find the expressions for

a. the ball's initial speed in terms of the gravitational acceleration () and the maximum height () and;

b. the height of the ball when it has speed () in terms of its current height (), the gravitational acceleration (), and the maximum height ()

At the start of a basketball game, a referee tosses a basketball straight into the air by giving it some initial speed. After being given that speed, the ball reaches a maximum height, above where it started. Using the conservation of energy, find expressions for (a) the ball's initial speed in terms of the gravitational acceleration, g and the maximum height and (b) the height of the ball when it has a speed v in terms of its  current height y, the gravitational acceleration g and the maximum height . 

A 48.1-kg athlete leaps straight up into the air from a trampolinewith an initial speed of 9.6 m/s. The goal of this problem is tofind the maximum height she attains and her speed at half maximumheight.
(a) What are the interacting objects and how do theyinteract?


(b) Select the height at which the athlete's speed is 9.6 m/s as y= 0. What is her kinetic energy at this point? What is thegravitational potential energy associated with the athlete?
kinetic energy J
potential energy J

(c) What is her kinetic energy at maximum height? What is thegravitational potential energy associated with the athlete?
kinetic energy J
potential energy J

(d) Write a general equation for energy conservation in this caseand solve for the maximum height. (Do this on paper. Yourinstructor may ask you to turn in this work.)

(e) Substitute and obtain a numerical answer.
m

(f) Write the general equation for energy conservation and solvefor the velocity at half the maximum height. (Do this on paper.Your instructor may ask you to turn in this work.)

(g) Substitute and obtain a numerical answer.
