Explanation:
I'll assume he started from rest, and the acceleration is constant.
We can solve this problem using the kinematics equation
where

#v_x# is the velocity (onedimensional) at time#t# 
#v_(0x)# is the initial velocity 
#a_x# is the constant acceleration 
#t# is the time
He starts with an initial velocity of
His (assumed to be constant) acceleration is thus
