t=0

. At

t=12\,\text{s}

it is at

(24\,\text{m},\,36\,\text{m})

, and at

t=24\,\text{s}

its velocity components are

(3\,\text{m/s},\,5\,\text{m/s})

in the

(x, y)

directions, respectively. If the drone’s acceleration remains constant, what is the magnitude of its average acceleration over the

24\,\text{s}

interval? (a)

0.18\,\text{m/s}^2

(b)

0.12\,\text{m/s}^2

(c)

0.06\,\text{m/s}^2

(d)

0.09\,\text{m/s}^2
