Q: A Robot began moving from point A in a straight line at 6 p.m with an initial speed of 3 m/s. One second later , the speed of the Robot became equal to 4 m/s. Find the acceleration of the Robot at the end of the 2nd second if its speed changes by the law s(t) = a(t)^2 + 2t + b.
a) 1 m/s^2
b) -2 m/s^2
c) 0 m/s^2
d) -3 m/s^2
e) 4 m/s^2
a) 1 m/s^2
b) -2 m/s^2
c) 0 m/s^2
d) -3 m/s^2
