Calculus I Problem Help!

A particle, moving in a straight line, has an acceleration function of a(t) = 6t - 5cos t, where time is measured in seconds and distances in meters. The initial position was 11.6 m from the origin, and the initial velocity was 31. a) Find the velocity function b) Find the position function c) Find the average acceleration over the first 10 seconds, and enter that in the box below
