2. Print Tutorial Click Screen for Next Step Return to Main Menu A car is traveling at 30.0 m/s and can accelerate at a rate of 5.5 m/s 2. How far does the car travel in 8.0 sec?

3. Print Tutorial Click Screen for Next Step Return to Main Menu List the variables and their values. v i = 30.0 m/s a = 5.5 m/s 2 t = 8.0 sec d = ?

4. Print Tutorial Click Screen for Next Step Return to Main Menu Use equation III d = v i t + ½ at 2 v f is not mentioned in the problem.

5. Print Tutorial Click Screen for Next Step Return to Main Menu Substitute the known values. d=(30.0m/s)(8.0sec)+ (1/2)(5.5m/s 2 )(sec) Solve for the unknown variable. d = 416 m

6. Print Tutorial Click Screen for Next Step Return to Main Menu Section 2 What is the initial velocity of an electric car that accelerates at 1.4 m/s 2 for 8.0 sec. The distance traveled is 400.0 m. a) 19.4 m/s b) 23.6 m/s c) -182.4 m/s d) 147.2 m/s

7. Print Tutorial Click Screen for Next Step Return to Main Menu List the variables and their values. a = 1.4 m/s 2 t = 8.0 sec d = 400 m v i = ?

8. Print Tutorial Click Screen for Next Step Return to Main Menu Use equation III d = v i t + ½ at 2

9. Print Tutorial Click Screen for Next Step Return to Main Menu Substitute the known values. 400m= v i (8.0sec) + (1/2)(1.4m/s 2 )(8.0sec) 2

10. Print Tutorial Click Screen for Next Step Return to Main Menu Solve for the unknown variable. If you chose b), try again. If you chose c), try again. If you chose d), try again. If you chose a), you are correct. v i = 19.4 m/s
