A 75 kg ball carrier is running to the right at 6.5 m/s. An 80 kg defender is chasing the ball carrier running at 7.0 m/s. The defender catches the ball carrier in a completely inelastic collision. What is the final speed of the defender/ball carrier mass

    6.758V

    Explanation:

    The computation of the final speed of the defender/ball carrier mass is shown below:-

    Data provided in the question

    Measurement of ball = 75 kg

    Right m/s = 6.5 m/s

    Defender = 80 kg

    Carrying running 7.0 m/s

    Based on the above information, the final speed of the defender or ball carrier mass is

    As we know that

    Conservation of momentum is

    = Ball in Kg * Right m/s + Defender in Kg * running m/s

    = 75 * 6.5 + 80 * 7

    = (75 + 80) V

    Therefore, the Final speed = 6.758V
