15. After landing, a jet airliner on a straight runway taxis to a stop with an average velocity of 3.0 1. If the plane takes 7.00s to come to a stop, what was the planes initial velocity and what was we acceleration during the stopping? [-19.4ms!, 2.78ms) 16. A drag racer travelling at 240kmh on a straight track deploys a parachute that provides a uniform acceleration that slows the racer to 20kmh in 12s. a) What is the racer's acceleration? b) How far does the racer travel in the 12s interval? [-5.1 ms. 433m)
