The Attempt at a Solution
If I consider a coordinate system with the -Y axis along the direction of force and X axis along a line perpendicular to it (except the direction of velocity vector) then this problem is equivalent to the usual projectile motion problem where a particle is projected from an elevation horizontally ( i.e velocity perpendicular to gravity ) .
So I can conclude that the path in the problem is parabolic i.e option b) which is indeed the given answer .
Now , when I tried to find the equation of trajectory , I am a bit lost .
In the usual X-Y coordinate system with 'm' representing the mass of the particle , we have ,
## x = 3t + \frac{1}{2}\frac{4}{m}t^2##
## y = 4t - \frac{1}{2}\frac{3}{m}t^2##
I am finding it difficult to solve the above equations so as to get the relation between x and y .
Any sincere help is very much appreciated .
Thanks .
