29. A sports car enters a highway on-ramp at 15.0 m/s. If the car accelerates at 2.75 m/s2 for 8.0 s, what is the displacement of the car? 30. A ball is rolling up an incline at 7.2 m/s to the right. After 9.3 s, the ball is rolling at 3.9 m/s to the left. Find the acceleration of the ball. 31. Determine Bob's initial velocity if he accelerates at 2.01 m/s2 for 6.57 s and traveling 57.9 m . 32. Determine Alice's final velocity if she accelerates at 1.22 m/s2 while traveling 25.8 m over 3.56 s. Page 18 of 24
