Hey
I have a moving Ball
- The Ball has an InitialSpeed V_i
- The Ball has a TargetSpeed V_t
Every second:
- Ball is displaced V_i number of pixels
- V_i is multiplied by deacceleration D ( D is a number between 0 - 1 )
...
I need an expression, returning how many seconds it takes before reaching TargetSpeed V_t ( V_t is allways lower or equal to V_i )
( Time is integer only )
...
Im quite rusty when it comes to math, but i think i know where to start with this:
V_i * ( D )^x <= V_t
Now i need to isolate the X?
However im not sure how to do that, or if this is what i need to do at all.
Pleace correct me if im wrong.
EDIT:
Darn, i just noticed that this Sub Forum ( Math ) reads "No math help"
Maybe a Moderator could move this thread to an appropriate Sub Forum?
