A particle is projected with a speed `10sqrt(2)` making an angle `45^(@)` with the horizontal . Neglect the effect of air friction. Then after 1 second of projection . Take `g=10m//s^(2)`.A. the height of the aprticle above the point of projection is `5m`.B. the height of the particle above the point of projection is `10m.`C. the horizontal distance of the particle from the point of projection is `5m`.D. the horizontal distance of the particle from the point of projection is `15m`. |

Answer» Correct Answer - A `y=u_(x)t-(1)/(2)."gt"^(2)=10xx1-5xx1^(2)=5m` `x=u_(x)t=10xx1=10m` |
