ACI: SPH3U 1-D Kinematics 33. While approaching a red light, a driver applies the brakes. If the car brakes at an acceleration of 2.80 m/s?[S] and it takes 6.75 s for the car to come to rest, what was the car's initial velocity? 34. An airplane speeds up from 225 m/s to 319 m/s while travelling 3460 m. a. Calculate its acceleration. b. Calculate how much time was needed for this acceleration. 35. Determine how far a car travels while slowing down at 5.56 m/s2 from 55.7 km/h to 14.7 km/h. Page 19 of 24
