Question

Uniform linear motion 5. (10 pts) A car moves with a constant velocity along a straight road. Its position is xi 0 m atti-0 and is x2 30 m at t2 3s a. what is the cars velocity at t = 1 s? b. What is the cars displacement between t 1.5 s and t2.5 s? 6. (15 pts) In an 8-km race, one runner runs at a steady 12 km/h and another runs at 14.5 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?
