ath The path r(t) = (t - sin t) i+ (1 - cos t) j describes motion on the cycloid x = t - sin t, y = 1 - cos t. Find the particle's velocity and acceleration vectors at t = 2 . and sketch them as vectors on the curve. . . ... The velocity vector at t = , is v 2 (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
