When Will Particle B Pass Particle A in 2 Particles, 1 Direction?

Click For Summary

Homework Help Overview

The discussion revolves around two particles moving in the same direction with different initial velocities and accelerations. The original poster asks for the time at which Particle B will pass Particle A, given their respective velocities and accelerations.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the kinematics formula for distance traveled by each particle and consider equating these distances to find the time at which Particle B passes Particle A. There is a question about the correct formulation of the equation based on the provided parameters.

Discussion Status

The discussion has progressed with participants confirming the setup of the equation to compare the distances traveled by both particles. Some participants express understanding of the approach, while others confirm the formulation of the equation.

Contextual Notes

There is a repetition of the problem statement in the posts, and the participants are working within the constraints of using kinematic equations to solve for time without providing a complete solution.

Two particles are at the same point at the same time, moving in the same direction. Particle A has an inital velocity of 6.4 m/s amd am acceleration of 1.7m/s^2. Particle B has an initial velocity of 2.2 m/s and an acceleration of 5 m/s^2. At what time will B pass A? Answer in units of s.

Use the following kinematics formula and equal the distances they travel. Then, solve for time.

[tex]d = V_it+ \frac{1}{2}at^2[/tex]
 
so its 6.4t+1/2*1.7t^2=2.3t+1/2*5t^2 ?
 
precisely :!)
 
got it thanks
