hey i attempted this question but i don't know if its right. can some one check for me and correct it?
If an antelope accelerates from rest in a straight line with a constant acceleration of 1.71 m/s2 how long in seconds does it take the antelope to reach a speed of 26.1 m/s ?
Velocity initial=0
Velocity final= 26.1m/s
acceleration=1.71m/s2
time=?
a=vfvi/t
t=26.1/1.71
t=15.26

physics 
MathMate,
The answer is correct.
"with a constant acceleration of 1.71 m/s2"
your calculation is justified
t=(vfvi)/a
=(26.10) (m/s) / 1.71 (m/s/s)
= 15.26 s.
