Motion along a line multiple choice questions that i don't understand at all. i'm really stuck on these. help is appreciated (2/2)

Suppose v(t) = 3t 9 on the interval [0, 5]. What is the total distance traveled on [0, 5]? O 19.5 0 13.5 0 12.5 0 7.5 The velocity of a particle on the time interval 0 S x $ 3 is v(x) = e .5x, where v(x) is in cm/s. What is the average velocity for the interval? O 2.321 O 2.436 O 3.425 O 3.524If acceleration is a(t) = 5' and initial velocity is v(0) = 4, what is an integral function that could be used to find the velocity at any point in time?
