# Finding intial velocity given vertical and horizontal displacement

1. Oct 11, 2009

what is the initial velocity when:
Horizontal displacement= 1.51
Vertical displacement= -.273
angle launched= 36

could someone at least tell me the equations i need to use, because i am totally lost

Is there any units for the displacements.
Do you know, how to resolve the velocity in to vertical and horizontal components?
Out of this, which component remains constant?
What are the kinematic equations?
