Question

the parabolic path of a projectile is represented by y= x /√3 - x square / 60 in M.K.S units .it's angle of projection is ( g = 10 ms power -2).

answer please..step by step​

Answer 1

Explanation:

f1(x,y)=3x+4y-6/5+12x-5y-3/13=0

f2(x,y)=3x+4y-6/5-12x-5y-3/13=0

Now let us assume we calculated the above equations for angle A of triangle ABC

To determine which of the above two equations, you first need to find out the points B and C,by solving for lines l1,l3 and l2,l3 and then evaluate

F=fi(B)×fi(C) for i=1,2

the one with F<0 is the equation of internal angel bisector
