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=vf-vi/t
t=26.1/1.71
t=15.26

    The answer is correct.

    "with a constant acceleration of 1.71 m/s2"
    your calculation is justified
    t=(vf-vi)/a
    =(26.1-0) (m/s) / 1.71 (m/s/s)
    = 15.26 s.
