1. SpaceX rocket acceleration is expressed as a function of time given as a = bt, where b is a positive constant. (a) Find position function x(t). And (b) Find the postion and velocity at t = 5 sec. if x = 0, and v = 0 at t = 0 and b = 3 m/s3.

2. A particle travels with velocity v = (8 m/s2) t - 7 m/s. (a) Find the average acceleration for two 1-s intervals, one beginning at t = 3 s and the other beginning at t = 4 s. And (b) Sketch v versus t. (c) What is the instantaneous acceleration at any time?
