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?

  • physics -

    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.
