SUMMARY

The discussion centers on solving a kinematics problem involving a particle with a constant acceleration of -8 m/s². Key data points include the position x=20 m at t=4 s and x=4 m when the velocity v=16 m/s. Participants suggest using standard constant acceleration equations to determine the time when the velocity is zero and to calculate the velocity and total distance traveled at t=11 s. The approach emphasizes establishing initial conditions for position and velocity.

PREREQUISITES
  • Understanding of kinematic equations for constant acceleration
  • Familiarity with concepts of velocity and acceleration
  • Ability to manipulate algebraic equations
  • Basic knowledge of particle motion in physics
NEXT STEPS
  • Study the derivation and application of the kinematic equations
  • Learn how to calculate time of flight and maximum height in projectile motion
  • Explore the implications of negative acceleration on motion
  • Investigate graphical representations of velocity and acceleration over time
USEFUL FOR

Students studying physics, particularly those focusing on kinematics, as well as educators seeking to clarify concepts related to particle motion and acceleration.

3 Days... and i still can't figure out 'how','why' and 'wat' is the answer...


THE ACCELERATION OF A PARTICLE IS DEFINED BY THE RELATION a=-8m/s^2.
KNOWING THAT x=20m when t=4s and that x=4m when v=16m/s,
determine:

a) the time when the velocity is ZERO.
b) the velocity and the total distance traveled when t = 11s...

THANK YOU...

welcome to pf!

hi chrishatch! welcome to pf! :smile:

(try using the X2 icon just above the Reply box :wink:)

always start questions like this by saying "let x and v be x0 and v0 at t = 0" …

then use the standard constant acceleration equations with the given data …

what do you get? :smile:​
