The distance between the location of thepitcher and homeplate (where the batter stands) is 60.5 feet. Give EXACT answers, unless instructedotherwise.(a) Calculate the horizontal velocity of the baseball at time t; this is the function x'(t)ft/sec.(b) What is the horizontal velocity of the baseball when it passes over homeplate?ft/sec (c) What is the vertical velocity of the baseball at time t; this is the function y'(t).?x: t==
