Q1Kinematics of Motion in a Straight LineFree sample

Fig. 1

A woman walks in a straight line. The woman’s velocity $t$ seconds after passing through a fixed point $A$ on the line is $v\text{ m s}^{-1}$ . The graph of $v$ against $t$ consists of 4 straight line segments (see diagram). The woman is at the point $B$ when $t = 60$ . Find

(i)

the woman’s acceleration for $0 < t < 30$ and for $30 < t < 40$ ,

(ii)

the distance $AB$ ,

(iii)

the total distance walked by the woman.
