Physics

Example:

In the given plot, for $t∈(0,10)$,

Displacement $s=−4−0=−4$

Hence, average velocity is given by $v=s/t=−4/10=−0.4m/s$

In the time interval $t=0$ to $t=5$, the acceleration $a=5−010−0 =2m/s_{2}$

Hence $T=m(g+a)$

$T=12×(10+2)=144N$

In the time interval $t=5$ to $t=10$, the acceleration $a=0$

Hence $T=mg=12×10=120N$

In the time interval $t=10$ to $t=15$, the acceleration $a=15−1030−10 =4m/s_{2}$

Hence $T=m(g+a)$

$T=12×(10+4)=168N$
