Heading 1 Heading 2 Paragraph Is Styles After it is cut from the blank material, the resulting workpiece is then ejected above the power hacksaw to two polishing stations. The heights reached by the workpieces above the hacksaw to the two polishing stations are given by H, (t) and H2(t) by the following equations, respectively: Hi(t) = 20t - 2t2 H2(t) = 35 log 3t2 A. What is the acceleration of the work pieces in each case? B. What is the maximum height the work pieces attain in each case? The velocity v(t), of the work pieces as thrown up is given by the following equation: v(t) = 5 - 3et C. Find an expression for the distance travelled by the workpiece. D. Determine the distance travelled by the workpiece within the first 3 seconds. O O W P 55 acer ASPIRE F4 F6 F7 F8 F9 F10 F11 F12 Numlk LA % A & 8 9 E 5 6 8 9 O R Y U 4 O P UT
