Kinematics of motion in a straight line: calculation question

4 marksChallenge

The acceleration of a particle moving in a straight line is given by $a = 2t - 2$ m/s $^2$ , where $t$ is the time in seconds. Given that the initial velocity is $u = 1$ m/s, find the velocity when $t = 5$ s.

(a)
Find the velocity at $t = 5$ s.
