Position and time interval of a particle

Click For Summary
SUMMARY

The position of a particle moving along the y-axis is described by the equation y = 0.20m + (8.0m/s) t - (10 m/s2) t2. The particle is not in constant motion; it has an instant when its velocity is zero. By calculating the derivative dy/dt and setting it to zero, one can determine the specific time at which the particle momentarily stops moving.

PREREQUISITES
  • Understanding of calculus, specifically differentiation
  • Familiarity with kinematic equations
  • Knowledge of particle motion along a single axis
  • Basic grasp of instantaneous velocity concepts
NEXT STEPS
  • Learn how to differentiate polynomial functions
  • Study kinematic equations for uniformly accelerated motion
  • Explore the concept of instantaneous velocity in physics
  • Investigate the implications of zero velocity in particle motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and motion analysis, as well as educators teaching calculus and kinematics.

Homework Statement


The position of a particle moving along the y-axis has a position given by y = 0.20m + (8.0m/s) t - (10 m/s2) t2. is there any time interval during which the particle is not moving?


Homework Equations





The Attempt at a Solution


I said No but I'm not sure why exactly it is never moving.

There is one instant when the particle is not moving. Find dy/dt and equate it to zero to get that instant.
