    Time
In summary, the conversation discusses ways to calculate time given final velocity, initial velocity, acceleration, and distance. It also mentions the concept of acceleration and the formula for calculating speed. A specific scenario is given where two friends travel at different speeds and the question of how long one will wait for the other is raised.

How do I find time when I already have final velocity, initial velocity, acceleration and distance?

It depends, is the acceleration constant?Do you have any ideas how you might find the time?What is the definition of acceleration?
 
  • #3
Here's the question, Me and my friend drove 50 km. I travel at 90 km/hr, my friend traveled at 95 km/hr. How long will my friend wait for me at the end of the trip?
 
  • #4
If you drove for 1 hour, how far would you travel? What about your friend?

What is the formula for calculating speed if you know distance traveled and the time it took?
 
  • #5
An interesting idea is to convert each into hours per km, then just *50.
 

FAQ: Find Time: Initial Velocity, Final Velocity, Acceleration, Distance

What is initial velocity?

Initial velocity is the velocity of an object at the beginning of its motion. It is typically denoted by the symbol "v0" or "u".

What is final velocity?

Final velocity is the velocity of an object at the end of its motion. It is typically denoted by the symbol "v" or "uf".

What is acceleration?

Acceleration is the rate of change in an object's velocity over time. It is typically denoted by the symbol "a".

What is distance?

Distance is the total length traveled by an object. It is typically denoted by the symbol "d".

How do you use these variables to calculate time?

The equation for finding time using initial velocity, final velocity, acceleration, and distance is: t = (v - u) / a, where "t" is time, "v" is final velocity, "u" is initial velocity, and "a" is acceleration. Alternatively, you can rearrange the equation to solve for any of the variables, depending on what information you have available.
