Question

In the velocity-time graph, the distance travelled by the particle between $1.0$ sec and $4.0$ sec, is approximately

• A. $50m$
• B. $40m$
• C. $30m$
• D. $20m$

Answer 1

Answer: (B)

$40m$

In a velocity time graph , the area of the graph gives the total displacement of the graph
Area of the graph $=$ Area of the rectangle + Area of the triangle
$=3\times 11.25+\frac{1}{2}\times 3\times (15-11.25)$
$=39.375$
$\approx 40m$
