How Far Will Your Slush Ball Travel?

[junkigal]

you are standing on top of your snow fort, defending yourself from a horde of evil attackers. if you hurl a 2.1 kg slush ball at an angle of 35 degrees from the horizontal, and a velocity of 15 m/s, how far will it travel before it hits the ground? assume you launch it from a height of 1.6 m above the ground..

its is so simple yet so complex for me!

there are few eqns which should be posted: one that relates distance to acceleration,velocity, and time. The others relate the vertical and horizontal velocities to the angle and the velocity at which the snowball is thrown.
