    A player kicks a football of mass 0.5 kg and the football begins to move with a velocity of 10 m/sec. If the contact between the leg and the football lasts for 1/50 sec, then the force acted on the football should be

    A) 2500 N             

    B) 1250 N

    C) 250 N               

    D) 625 N

    Correct Answer: C

    Solution :

    Force on the football \[F=m\frac{dv}{dt}\] \[F=\frac{m({{v}_{2}}-{{v}_{1}})}{dt}\,\,=\,\,\frac{0.5\times (10-0)}{1/50}\,\,=\,\,250\,\,N\]
