plz mark it as brainliest answer

Answer 2

Step-by-step explanation:

speed of a body is defined as position upon time

you can differentiate if you are class 11 student or follow my method:

find area

$\frac{1}{2} \times 2 \times 16$

is area of triangle

there are 2 triangles therefore,

$32$

is area of triangles

middle portion area:

$4 \times 16$

$64$

total area is 96

the velocity is the slope which is equal to 4 m/s

thus your answer is velocity is 4ms
