Need help with gravity distance acceleration problem0-equation

Click For Summary
SUMMARY

The discussion focuses on solving a physics problem related to gravity, specifically calculating the time it takes for an object to fall a certain distance under acceleration. The user, identified as kill_shot, is attempting to determine the total time for a rock dropped from rest, given that it takes 1.5 seconds to fall half the distance. Participants emphasize the importance of utilizing standard kinematic equations, which are commonly found in physics textbooks, to derive the solution effectively.

PREREQUISITES
  • Understanding of kinematic equations in physics
  • Familiarity with concepts of acceleration due to gravity
  • Basic knowledge of initial velocity and its implications
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Review standard kinematic equations for uniformly accelerated motion
  • Study the concept of free fall and gravitational acceleration (9.81 m/s²)
  • Practice solving problems involving time, distance, and acceleration
  • Explore graphical representations of motion under gravity
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of motion under gravity, particularly those tackling problems involving kinematics and free fall.

Need help with gravity distance acceleration problem0--equation

So I basically need an equation to give me time form the following variables:
initial velocity or v
acceleration or a
distance or x

i'm having a hard time with a rock being dropped taking 1.5 seconds to go half the distance, what about the whole time it will take..thanks

Welcome to Physics Forums kill_shot.

Before we can help you, you'll need to list the equations you know about and make an attempt at a solution.

There are 3 or 4 standard equations for this type of problem. Every physics textbook that deals with this stuff uses them. Start by looking at those equations.
