Finding Distance Traveled of Car with Constant Acceleration/Deceleration

Click For Summary
SUMMARY

The discussion focuses on calculating the total distance traveled by a car under constant acceleration and deceleration. The car accelerates at 1.8 m/s² for 10 seconds, travels at a constant speed for 12 seconds, and then decelerates at 1.9 m/s² until it stops. The initial calculation of 283.34 meters is questioned, prompting a request for detailed work and relevant equations used in the solution process.

PREREQUISITES
  • Understanding of kinematic equations for uniformly accelerated motion
  • Knowledge of how to calculate distance using acceleration and time
  • Familiarity with constant speed motion
  • Ability to apply deceleration concepts in motion problems
NEXT STEPS
  • Review kinematic equations: \(d = vt + \frac{1}{2}at^2\)
  • Learn how to calculate distance during constant speed segments
  • Study the effects of deceleration on distance traveled
  • Practice similar problems involving multiple phases of motion
USEFUL FOR

Students studying physics, particularly those focusing on kinematics, as well as educators looking for examples of motion problems involving acceleration and deceleration.

Homework Statement


A car starting from rest moves with a constant acceleration of 1.8 m/s2 for 10 s, then travels with a constant speed for another 12 s, then finally slows to a stop with a constant deceleration of 1.9 m/s2. How far does it travel?

Homework Equations





The Attempt at a Solution


I tried this and got 283.34 m. I have nooo clue where to start with this. HELP!

Please show your work so we can see what you did. This is the only way we can point out errors.
 


How did you get 283.34m? What relevant equations are you using?
