A particle is projected in the x-y plane with y-axis along vertical. Two second after projection the velocity of the particle makes an angle 45° with the x-axis. Four second after projection, it moves horizontally. Find the velocity of projection.

I have assumed the initial velocity to be u and the angle of projection to be theta.
You just have to split the projection in the horizontal and vertical directions and use the equations.
Gather all the variables and conditions and find the initial velocity as done in the solution. In my solution their might be some variables which might not have any use, so just ignore them please.
I hope you understand the concept and approach. All the best!
