Consider the position vs time graph for a moving car below. Determine the car\'s average speed 403------ 30 20 10 1 2 3 4 5 6 t(s) (Points: 1) o 10 m/s o 0.5 m/s o 2 m/s o 5 m/s 1 of 10 Next Save Answers Submit for Grading

Solution

1 ) car average speed = total distance tranvelled / total time = 30m / 6 sec = 5 m/sec

2 ) average velocity = total displacement / time = 0 , since he came back to the starting point , he cover to displacement

3) Object 2 finishes a head of Object 1

4)velocity V = distance / time = 15/ 6 = 2.5 m/sec , position after 10 sec = V * time = 2.5 * 10 = 25 m

5) distance = displacement ; when we move in a straight line ; i,e you walk 20 feet from teacher desk and sit

6)acceleration = change in velocity / time = 40 - 30 / 1sec or 45-40 /1sec = 5 km/h/s

7) A greater distance than the second before ; since acclerating bodys cover more distance with every sec time.
