A particle is projected horizontally will speed `20 ms^(-1)` from the top of a tower. After what time velocity of particle will be at `45^(@)` angle from initial direction of projection.

A particles is projected horizontally with a speed v from the top of a plane inclined at an angle tehta to the horizontal as shown in the figure. (a) Hwo far from the point of projection will the particle strike the plane ? (b) Find the time taken by the particel to hit the plane. (c) What is the velocity of particle just before it hits the plane ?
