A projectile is launched over level ground at a launch angle of 70o with an initial velocity
vo. At some later time while the projectile is on its way to the peak in its trajectory, its
velocity vector makes an angle of 50o with respect to the horizontal. What is the
magnitude of the projectile’s horizontal velocity at that point?

    This is not a place to dump your homework. I doubt you will get much help unless you start showing some work on your part. And Ms Sue is right. Using umpteen screen names only makes it less likely you will get help.
