Answer:
As Per Provided Information
Moving body has 2m/s² acceleration
Time taken by body is 4 second
We are asked to find the 'change in velocity' ( ∆V) by the body.
Formula Used here
[tex] \boxed{\bf{\Delta \: V \: = acceleration \: \times time \:}}[/tex]
Substituting the given value
[tex] \sf\longrightarrow\Delta\:V \: = 2 \times 4 \\ \\ \\ \sf\longrightarrow\Delta\:V \: =8m {s}^{ - 1} [/tex]
Therefore,
