Answer 2

According to the given velocity-time graph we are asked to calculate the displacement of the body in the time interval 4-5 seconds.

Explanation: To calculate the distance or displacement from a velocity-time graph we have to calculate the area under the curve. Let's do it!

Required solution:

$:\implies \sf s \: = Area \: under \: curve \\ \\ :\implies \sf Distance \: = Area \: under \: curve \\ \\ :\implies \sf Distance \: = Area \: of \: square \\ \\ :\implies \sf Distance \: = Side \times Side \\ \\ :\implies \sf Distance \: = (5-4) \times (1-0) \\ \\ :\implies \sf Distance \: = 1 \times 1 \\ \\ :\implies \sf Distance \: = 1 \: metre \\ \\ :\implies \sf Displacement \: = 1 \: metre$

Henceforth, displacement = 1 m. Therefore, option B) is correct!
