An aeroplane is flying in a horizontal direction with a velocity `600 km//h` at a height of 1960 m. When it is vertically above the point A on the ground, a body is dropped from it. The body strikes the ground at point B. Calculate the distance AB.A. `3.33 km`B. `4.33km`C. `5.33km`D. `6.33km` |
Answer» Correct Answer - A `t = sqrt((2h)/(g)) = sqrt((2 xx 1960)/(9.8)) = 20s` `:.` Horizontal distance `= 600 xx (20)/(60 xx 60) km = 3.33 km` |
