The position of a particle at time t is given by the function r(t) = (t^3 + t^2 -2, 2t^2 +3t). Find each of the following at time t = 2. (a) a_r the tangential component of acceleration. (b) a_N, the normal component of acceleration. (c) Is the particle speeding up or slowing down when t = 2? Explain.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
