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