a low velocity mortar round is fired upward at an angle of 50° from the horizontal with a launch velocity of 40 m/s

    What is the question.?
    Do they want to know the range?

    R = (Vo^2/g)*sin(2A)

    2A = 100 degrees

  • physics -

    how long before it hits the ground!

  • physics -

    Time of flight:
    T = 2*Vo sinA/g
    A = 50 degrees
    It spends Vo sinA/g going up and an equal amount of time coming back down
