Answer:
<em>The velocity of Heather and Matthew is 1.6 m/s eastward.</em>
Explanation:
<em>Velocity</em>: This is the time rate of displacement. The S.I unit of velocity is m/s.
Velocity is a vector quantity because it can be represented by magnitude and as well as direction. The mathematical expression for velocity is given below
V = d/t...................... Equation 1
Where V = velocity of Heather and Matthew, d = displacement of heather and Matthew, t = time.
<em>Given: d = 72 m eastward, t = 45 s.</em>
Substituting these values into equation 1
V = 72/45
V = 1.6 m/s eastward.
<em>Thus the velocity of Heather and Matthew is 1.6 m/s eastward.</em>
