Homework Help: Projectile motion

  1. Jul 5, 2011 #1
    A particle is projected with a velocity of 146m/s at an elevation of 35degree.
    max height= 357.8, t=17.1s horizontal distance= 2041.8m

    the question is find the velocity and direction of motion at a height of 120m
    i got v= 137.72, but what is the meaning of the direction of motion at a height of 120m, the correct answer is 29.72degree

    thank you

    It means at what angle the particle is moving. 29.72 degrees presumably means 29.72 degrees from the horizontal.
