Problem

A boat changes its velocity from

(4.0\,\hat\imath + 0\,\hat\jmath)\,\text{m/s}

(2.0\,\hat\imath + 3.0\,\hat\jmath)\,\text{m/s}

5.0\,\text{s}

. What is the magnitude of the boat’s average acceleration during this interval? (a)

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

(b)

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

(c)

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

(d)

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