Questions
For ground to ground projection range of a projectile is 240 m and its angle of projection is 450. Then equation of its trajectory is
a
20 y =60 x - x2240
b
y = x -x2240 y=\sqrt{3}x-\frac{{{x}^{2}}}{120}
c
30 y =y=\frac{x}{\sqrt{3}}-\frac{{{x}^{2}}}{480}x - x280
d
y = 30 x - x280\vec{u}\,\,=\,\,\left( 20\hat{i}+20\sqrt{3}\hat{j} \right)
detailed solution
Correct option is B
y =x tan 450 (1 - x240) =x - x2240Talk to our academic expert!
