4)
the arrow touches the ground when the heigth is 0
so we need to replace h=0 and solve for t
<em>the arrow tuches the ground at 3.4 seconds</em>
5)
replacing
<em>solve for m</em>
<em>the mass is 13.50Kg</em>
<em />
solve (3sqrt(2))/(sqrt(3) + sqrt(6)) - (4sqrt(3))/(sqrt(2) + sqrt(6)) + (sqrt(6))/(sqrt(3) + sqrt(3))
