Answer 2

Answer:

Option C is the answer.

Explanation:

Just find the area of the V vs. T graph to find the displacement covered by the object.

From t=0 to t=9:-

$from \: t = 0 \: to \: t = 7 \\ area \: of \: trapezium \: = \frac{h}{2} (a + b)$

$so \: area \: is \: 13.5 \: + \: area \: of \: triangle \: \\ so \: answer \: is \: 15 .5m.$
