JEE Main & Advanced Physics Two Dimensional Motion Sample Paper Topic Test - Two Dimensional Motion

  • question_answer
    An aeroplane is flying horizontally with a velocity of 600 km/h at a height of 1960 m. When it is vertically at a point A on the ground, a bomb is released from it. The bomb strikes the ground at point B. The distance AB is

    A) 1200 m

    B) 0.33 km

    C) 3.33 km

    D) 33 km

    Correct Answer: C

    Solution :

    [c] Horizontal displacement of the bomb AB = Horizontal velocity × time available \[AB=\,u\times \sqrt{\frac{2h}{g}}\]\[=600\times \frac{5}{18}\times \sqrt{\frac{2\times 1960}{9.8}}\]\[=3.33\,Km.\]
