![Uniform linear motion (10 pts) A car moves with a constant velocity along a straight road. Its p xi = 0 m atli = 0 and is x2-30 rn at r2-3s. 5. a. What is the cars velocity at t 1 s? b. What is the cars displacement between t 1.5 s and t 2.5 s? 6. (15 pts) In an 8-km race, one runner runs at a steady 12 km/h and another runs at km/hr. If they start at the same instant, how far from the finish line is the slower runner when the faster runner finishes the race? 7. (20 pts) P 2.2. Show all calculations. [(vave)te Grandm.-48 mph; (Vavetrom Grandms -50 mph] Constant acceleration motion 8. (10 pts) A car can go from 0 to 60 mph is 12 s. A second car is capable of twice the acceleration of the first car. Assuming that it could maintain the same acceleration at higher speeds, how much time will this second car take to go from 0 to 120 mph? 9. (10 pts) P 2.14 10. (20 pts) P 2.19.
