Two grenades, A and B, are thrown horizontally with different speeds from the top of a cliff 70 m high. The speed of A is 2.50 m/s and the speed of B is 3.40 m/s. Both grenades remain in air for 3.77 s. Assume that the acceleration due to gravity is 9.86 m/s^2. What is the distance between A and B if they are thrown along the same straight line?

  • Physics -

    The horizontal distances are given by
    Da(t) = 2.5t m
    Db(t) = 3.4t m
    Distance between A and B after 3.77 seconds is therefore
    Distance = Db(3.77)-Da(3.77)
    assuming the grenades are thrown in the same straight line in the same direction.
    The acceleration due to gravity has no bearing on the distance between A and B, if air resistance can be ignored.
