SUMMARY

The discussion focuses on calculating the average velocity of a remote-controlled vehicle that starts with an initial speed of 1.0 m/s and accelerates backward at 0.08 m/s² for 4.0 seconds. The average velocity is determined using the formula Vavg = deltaD/deltaT, where deltaD represents the displacement. The user attempts to calculate deltaD using the equation deltaD = (V2² - V1²) / (2a) and arrives at a displacement of 0.625 meters. The calculation is confirmed to be correct based on the provided parameters.

PREREQUISITES
  • Understanding of kinematic equations, specifically Vavg = deltaD/deltaT
  • Knowledge of initial speed and acceleration concepts
  • Ability to manipulate equations involving displacement and acceleration
  • Familiarity with basic physics principles related to motion
NEXT STEPS
  • Review kinematic equations for uniformly accelerated motion
  • Learn how to calculate displacement using initial speed and acceleration
  • Explore the implications of negative acceleration on average velocity
  • Practice similar problems involving average velocity and acceleration
USEFUL FOR

Students studying physics, particularly those focusing on kinematics, as well as educators looking for examples of average velocity calculations in motion problems.

1. Homework Statement

Calculate the average velocity for a remote controlled vehicle that starts with a speed of 1.0 m/s [forward] and then accelerates at 0.08 m/s2 [backward] for 4.0 s


2. Homework Equations

Vavg=deltaD/deltaT

3. The Attempt at a Solution

I'm unsure of how to go about this even though it seems its an easy question. Is there enough information to even solve it? Wouldn't i need the amount of time that it travels forward? Thanks for any help

The equation you listed isn't all you need. What other motion equations do you know that might help you find delta d?
 
Delta d=(V2^2-V1^2)/2a?

Not sure if I am doing this right but
Delta d=(1.0^2-0.0^2)/2(0.8)
= 0.625m

I need some help is this correct?
