20An aeroplane is flying in horizontaldirection with a velocity of 540

1.	20An aeroplane is flying in horizontaldirection with a velocity of 540km/hr at a height of 2200 m. When itIs vertically above the ground, a bodyis dropped from it. What is the timetaken and how much horizontaldistance covered when the body hitsthe ground. Neglect air resistance."25 sec, 3156 m21 sec, 3176 mO 28 sec, 3166 m30 sec, 3186 m
Answer» $\color{red}\huge{\underline{\underline{GIVEN\dag}}}$ An AEROPLANE is moving with 540km/hr and 2200m above the ground. Height(H)-2200m Velocity(v)-540km/hr v-150 m/s $\color{red}\huge{\underline{\underline{SOLUTION\dag}}}$ We know that; $\color{blue}\boxed{Time(of\: flight\: of\: object)=\sqrt{\frac{2h}{g}}}$ Where, h-height g-accelaration due to GRAVITY( $10m/s^{2}$ $Time=\sqrt{\frac{2(2200)}{10}}$ $Time=20.9sec$ We ALSO know that; $\color{blue}\boxed{R(distance)=v\sqrt{\frac{2h}{g}}}$ $R=150×20.9$ $R=3146m$ HOPE THAT HELPS!! (pls check the calculations but this is the method)
