s=t^(2)-t+1
The equation of motion is given for a particle, when s is in meters and t is in seconds. Find (a) the velocity and acceleration as functions of t and(b) the acceleration after 1 second. For (a) I got v(t)=2t-1 and a(t)=2 but how do you find (b)?

since a(t) = 2 for all values of t such that t >= 0, this means a(1) = 2

basically the acceleration after 1 second is 2 m/s^2
