1. The problem statement, all variables and given/known data A baseball is bunted down the third base line leaving the bat from a height of .900m with initial v = 3.00 m/s at angle 20° above the horizontal. I calculated that x(range)= 1.72m t(total)=.61s vx=2.82 m/s vy=1.03 m/s -What is the speed of the ball before it hits the ground? -What is the max height of the baseball above the horizontal in this travel? -What is the ball's centripetal and tangential acceleration at max height? -What is the ball's centripetal and tangential acceleration at the instant just before the ball hits the ground? -What are the radiuses of the baseball path curvature at max height and at the point of grounding? (What does this question even mean?) 2. Relevant equations (y-y0)=V0yt+at2/2 v=v0+at ac=v2/R at=dv/dt 3. The attempt at a solution For calculating the max height, I keep getting y max as equal to .478 m, which makes no sense since its even less than the initial height... Anybody know what I am doing wrong? Additionally for for the speed before it hits the ground I'm pretty sure that means normal velocity, yet when I plug in the numbers to the equation I get a velocity of -2.98 m/s which really does not make sense. Regarding the centripetal acceleration, I just wanted to clarify if r(radius) would be equal to half of the distance traveled or not... And how to calculate tangential acceleration? I have no clue... Also what would the difference between the acceleration at max height and before it lands?
