Q. Figure shows four paths for a kicked football. Ignoring the effects of air on the flight, rank the paths according to initial horizontal velocity component, highest first
A) 1, 2, 3, 4
B) 2, 3, 4, 1
C) 3, 4, 1, 2
D) 4, 3, 2, 1
Explanation
(d) $R = \frac{u^{2}\sin{2\theta}}{g} = \frac{2u_{x}v_{y}}{g}$
$\therefore$ Range $\propto$ horizontal initial velocity $(u_{x})$
In path 4 range is maximum so football possess maximum horizontal velocity in the path
