A particle is projected in the `X-Y` plane. `2sec` after projection the velocity of the aprticle makes an angle `45%(@)` with the `X-`axis. `4sec` after projection, it moves horizontally. Find the velocity of projection (use `g = 10 ms^(-2))`.

A particle is projected in the X-Y plane. 2 sec after projection the velocity of the particle makes an angle 45^(@) with the X- axis. 4sec after projection, it moves horizontally. Find the velocity of projection (use g = 10 ms^(-2)) .

A particle is projected in the x-y plane with y-axis along vertical. Two second after projection the velocity of the particle makers an angle 45^(@) with the X-axis. Four second after projection. It moves horizontally. Find velocity of projection.

One second after the projection, a stone moves at an angle of 45^@ with the horizontal. Two seconds from the start, it is travelling horizontally. Find the angle of projection with the horizontal. (g=10 ms^(-2)) .

One second after the projection, a stone moves at an angle of 45@ with the horzontal. Two seconds from the start, it is travelling horizontally. Find the angle of projection with the horizontal. (g=10 ms^(-2)) .

A particle is projected with a speed u. If after 2 seconds of projection it is found to be making an angle of 45^@ with the horizontal and 0^@ after 3 sec, then:
