3 Days... and i still cant figure out 'how','why' and 'wat' is the answer....


THE ACCELERATION OF A PARTICLE IS DEFINED BY THE RELATION a=-8m/s^2.
KNOWING THAT x=20m when t=4s and that x=4m when v=16m/s,
determine:

a) the time when the velocity is ZERO.
b) the velocity and the total distance traveled when t = 11s.....

THANK YOU...

welcome to pf!

hi chrishatch! welcome to pf! :smile:

(try using the X2 icon just above the Reply box :wink:)

always start questions like this by saying "let x and v be x0 and v0 at t = 0" …

then use the standard constant acceleration equations with the given data …

what do you get? :smile:
