SUMMARY

The discussion focuses on rearranging the equation d = v1(t) + 1/2a(t)^2 to solve for time (t). The user initially received the incorrect rearrangement of t as -2 - v1/a. The correct approach involves recognizing the equation as a quadratic equation and applying the quadratic formula, t = (-b ± √(b² - 4ac)) / 2a, where the coefficients correspond to the terms in the equation.

PREREQUISITES
  • Understanding of basic algebraic manipulation
  • Familiarity with quadratic equations
  • Knowledge of the quadratic formula
  • Basic physics concepts related to motion
NEXT STEPS

The Attempt at a Solution


my friend told me it was "-2-v1/a =t" but i don't this is right and if it is right how did he get this?
