Question

Neglecting the air resistance, the time of flight of a projectile is determined by

$U_{v e r t i c a l}$
$U_{h o r i z o n t a l}$
$U = U_{v e r t i c a l}^{2} + U_{h o r i z o n t a l}^{2}$
$U = U {(U_{v e r t i c a l}^{2} + U_{h o r i z o n t a l}^{2})}^{1 / 2}$

The correct answer is: $U subscript v e r t i c a l end subscript$

Time of flight $equals fraction numerator 2 u sin invisible function application theta over denominator g end fraction equals fraction numerator 2 u subscript y end subscript over denominator g end fraction equals fraction numerator 2 cross times u subscript v e r t i c a l end subscript over denominator g end fraction$
