The function s(t)=t(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}+tlnt gives the position from time [1,e] find:

a. the velocity at time t

b. the acceleration at time t

c. describe the motion of the object: when is it moving forward or moving backward. also compute the total distance traveled during the interval

d. when is the object accelerating and when is it decellerating

------------------------------------------------------------

my work

s(t)=t^{2}+tlnt

v(t)=2t+1+lnt

a(t)=2+(1/t)

Part a answer. v(t)=2(t)+1+lnt

part b answer a(t)=2+(1/t)

-------------------

Are my answers for a and b correct? And how would I find parts c and d.

Thank you!
