Please help me this problems and also write the numbers of each question

20. DETAILS SCALCET9 13.4.013. Find the velocity, acceleration, and speed of a particle with the given position function. r(t) = e (cos(t) i + sin(t) j + 6tk) v(t) = a(t) = IV(t)| =19. DETAILS SCALCET9 13.3.019. Consider the following vector function. r(t) = (5t2, sin(t) - t cos(t), cos(t) + t sin(t)), t > 0 (a) Find the unit tangent and unit normal vectors T(t) and N(t). T(t) = N(t) (b) Use the formula K(t) = IT'(t) | to find the curvature. Ir' (t) 1 K (t) = Submit
