(d) Recall that the speed of the baseball at time tis s(t)=√[x'(t)]2+ [y' (t)]2ft/sec. What is the speed of the baseball (in mph) when it passes over homeplate?
(e) At what time does the baseball hit the ground, assuming the batter and catcher miss theball? sec. (f) What is the magnitudeof the angle at which the baseball hits the ground?
Consider an object moving in the plane whose location at time tseconds is given by the parametricequations:x(t)=4cos(πt)y(t)=3sin(πt). Assume the distance units in the plane are meters.(a) The object is moving around an ellipse (as in the previous problem) with equation:10.12/12 points | Previous Answers
