A pine cone falls straight down from a pine tree growing on a 21.0^\circ slope. The pine cone hits the ground with a speed of 9.00 m/s. What is the component of the pine cone's impact velocity (a) parallel to the ground and (b) perpendicular to the ground?

Compute the vertical velocity from the distance that it falls, and resolv e that vector into directions along and perpendcular to the slope.

These are steps you should be able to do on your own by now.
