A shell is fired vertically upwards

  1. Sep 8, 2014 #1
    A shell is fired vertically upwards with a velocity of v1 from a ship moving with a velocity v2, a person on the shore finds the motion of the shell parabola. Show that the horizontal range is 2v1v2/g

    You know the formulas for the parabolic motion?

    Sure ^_^
    For the Range, the Time of Flight and the Max height :)

    A hint: the problem is like the case in which the shell is fired inclined at a specific angle θ, the angle is to be arctag v1/v2.

    Yes, because v1 is the velocity in the y direction and v2 the one in x direction.
