A62.0-kg athlete leaps straight up into the air from a trampoline with an initial speed of 9.6 m/s. the goal of this problem is to find the maximum height she attains and her speed at half maximum height. (a) what are the interacting objects and how do they interact? (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? (c) what is her kinetic energy at maximum height? 0 correct: your answer is correct. j what is the gravitational potential energy associated with the athlete? (d) write a general equation for energy conservation in this case and solve for the maximum height. e) write the general equation for energy conservation and solve for the velocity at half the maximum height.

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
