Calculating Rocket's Initial Velocity with 45-Degree Angle

[mitchy_boy]

Homework Statement

a rocket is fired at an angle of 45degrees from the horizontal, if it travels 22m(horizontally) for a total time of 1.9 secs, what is its intitial veritical and horizontal velocity?

Homework Equations

i tried using s=ut+.5at^2

The Attempt at a Solution

i came up with 1.2 for both horizontal and initial vertical velocity's

please help I am confused :S

Hi mitchy boy, welcome to PF.
In the projectile motion horizontal component of the velocity remains constant. In the problem horizontal displacement and time is given. From that find the horizontal component of the velocity.
