In the bottom of the ninth inning, a player hits a 0.15 kg ball over the outfield fence. The ball leaves the bat with a speed of 36 m/s and a fan in the bleachers catches it 7.2 m above the point where it was hit. Assuming frictional forces can be ignored, find (a) the kinetic energy of the ball when it is caught (b) its speed when it is caught.

  • A baseball slugger hits a pitch and watches the ball fly into the bleachers for a home run, landing h=8.5 m higher than it was struck

    A baseball slugger hits a pitch and watches the ball fly into the bleachers for a home run, landing h=8.5 m higher than it was struck. When visiting with the fan that caught the ball, he learned the ball was moving with final velocity vf= 39.45 m / s at an angle θf=29.5° below horizontal when caught. Assume the ball encountered no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial position.
