Probably because of the drag coefficient and the density of the liquid.
Answer:
Horizontal component = 16.8 m/s
Vertical component = 46.0 m/s
Explanation:
If we denote the initial velocity by <em>v</em> and the angle above the horizontal by <em>θ</em>,
the horizontal component of this initial velocity is given by


The vertical component is given by


Answer:
9.8m/s
Explanation:
acceleration due to gravity is independent of mass
perimeter of a rectangle = 2(L+B)
90=2(L+B)
90/2=L+B
45=L+B
