49 line with an 12-8. A particle moves acceleration of a-5/341n+30)m/s, where s us meters. Determine the particles velocaty when s- 2m, f st starts from rest when s-1 m Use a numenical method to evaluate the integral 12-17. The acceleration of a partacle as it moveés along a straaght line is given by a -2r-1)m/s. where t is in seconds. If s . 1 m and U-2 m/s when I 0, determine the partacles velocity and position when6s Also determine the total dastance the particle travels during this time penod. 12-52 The snowmobile moves along a straight course according to the e-tgraph.
