Eight years ago Farah was five years older to Sahil. At present Farah is twice Sahil’s age.

  1. By equations of motion,

    V = U+at

    V = [40 cos45 (i) + 40 sin45 (j)] + [g (-j) . 5]

    V = 40/√2(i) + 40/√2(j) – 50(j)

    V = 28.28(i) + 28.28(j) – 50(j)

    V = 28.28(i) – 21.72(j)

    V = √(28.28)²+(21.72)²

    V = 35.65 m/s
