Integrating the acceleration to get the velocity:
v(t) = t + 2t^(3/2)
v(9) - v(0) = 9 + 2*9^(3/2) = 9 +2 *27 = 63
An automobile accelerates from rest at 1+3squarert(t) mph/ sec for 9 seconds.
a) What is its velocity after 9 seconds?
b)how far does it travel in those 9 seconds?
Ok, i try doing the integral of that acceleration equation and get 27mph. However my book says its 63 mph. Can someone explain to me how to get 63? Thank you
