Kinematics of motion in a straight line — practice question
A woman travels along a straight line. Her velocity $t$ seconds after she passes a fixed point $A$ on the line is $v\,\text{m s}^{-1}$. The graph of $v$ against $t$ is made up of 4 straight-line segments (see diagram). The woman is at point $B$ when $t = 60$. Find
