Kinematics of motion in a straight line: calculation question

3 marksStandard

The displacement $s$ (in metres) of a particle moving in a straight line is given by $s(t) = 3t^2 + 2t$ , where $t$ is the time in seconds. Find the velocity of the particle at $t = 2$ seconds.

(a)
Calculate the velocity at the given time.
