A baseball is bunted down the third-base line leaving the batfrom a height of 0.850m with an initial velocity of 4.00m/s at anangle of 36.87° above horizontal
a) what is the speed of the baseball just before hitting theground? (answer by using mechanical energy conservation)
b) What is the ball's normal (centripetal) acceleration at themaximum height?
c) What is the baseball's tangential acceleration at maximumheight?
d) Answer b and c for the instant just before the ball hitsthe ground
e) What are the radiuses of the baseball path curvature at themaximum height and the point of grounding.
