ANSWER:Step 1 of 3
Initial velocity of \(50.0 \mathrm{~m} / \mathrm{s}\) at \(60 .\)
(a). The horizontal and vertical components of the shells initial velocity is given by
\(0 \times 5=2\)
Horizontal component \(=\cos (60) 0.0 \mathrm{~m} / \mathrm{s} 5 \mathrm{~m} / \mathrm{s}\).
\(0 \times 5=4\)
Horizontal component \(=\sin (60) 0.0 \mathrm{~m} / \mathrm{s} 3.30 \mathrm{~m} / \mathrm{s}\).
