    Just treat the x positions, velocities, and accelerations as separate from the y positions, velocities, and accelerations, and you can use the standard 2D equations for constant acceleration.

    |dw:1328338055066:dw|we know tht the time period is = 2 sin(theta) / g ... we are also give tht at max height t= 1.6s .. this means tht the time period is halved...!!

    krypton... the 15.696 m/s is the vertical component of a right angle velocity triangle where the angle opposite to the 15.696 is 27 degrees... you have to find the hypotenuse using the definition for Sine. I believe you get something in the order of 34.57 m/s.
