tegral Applications - Part 2 Time Taken:0:02:52 Priscilla Puentes: Attempt 1 Question 18 (3 points) The velocity of a particle on the time interval [0, 3] is v(t) = cos(2t), where v(t) is in cm/s. Find the average velocity for the interval. A Question 19 (3 points) If acceleration is a(t) =In(t2), and v(1) = 2, write an integral function that could be used to find the velocity at any point in time. Do not evaluate the integral.
