Multiplechoice 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 ) = ( α β t 2 ) where α = 44 . 8 m / s, β = 4 . 46 m / s 3 , and t is in seconds. Find the average acceleration in the time interval from t = 0 to 2 . 59 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 = 2 . 59 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 acceler ates uniformly from a speed of 51300 m / s to a speed of 4 . 68 × 10 6 m / s in a distance of 2 . 08 cm. What is its acceleration? Answer in units of m / s 2 ....
