Amajor league baseball pitcher throws a pitch that follows these parametric equations: x(t) = 142t y(t) = –16t2 + 5t + 5. the time units are seconds and the distance units are feet. the distance between the location of the pitcher and homeplate (where the batter stands) is 60.5 feet. give exact answers, unless instructed otherwise.(d) recall that the speed of the baseball at time t iss(t)=√ [x '(t)]2 + [y ' (t)]2ft/sec. what is the speed of the baseball (in mph) when it passes over mph
