Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points The velocity of a particle moving along the x axis varies in time according to the expression v ( t ) = ( - t 2 ) where = 40 . 1 m / s, = 3 . 96 m / s 3 , and t is in seconds. Find the average acceleration in the time interval from t = 0 to 1 . 82 s. Answer in units of m / s 2 . 002 (part 2 of 2) 10.0 points Determine the acceleration of the particle at t f = 1 . 82 s. Answer in units of m / s 2 . 003 (part 1 of 2) 10.0 points An electron in the cathode ray tube of a tele- vision set enters a region where it accelerates uniformly from a speed of 34400 m / s to a speed of 4 . 93 10 6 m / s in a distance of 2 . 9 cm. What is its acceleration? Answer in units of m / s 2 ....
