An aging coyote cannot runfast enough to catch a roadrunner.He purchases oneBay a set of jet-powered rollerskates, which provide a constanthorizontal acceleration of15.0 m/s2 (Fig. P4.78). The coyotestarts at rest 70.0 m fromthe edge of a cliff at the instantthe roadrunner zips past in thedirection of the cliff. (a) Determinethe minimum constant speed the roadrunner musthave to reach the cliff before the coyote. At the edge ofthe cliff, the roadrunner escapes by making a suddenturn, while the coyote continues straight ahead. The coyotesskates remain horizontal and continue to operatewhile he is in flight, so his acceleration while in the airis 115.0i^ 2 9.80j^ 2 m/s2. (b) The cliff is 100 m above theflat floor of the desert. Determine how far from the baseof the vertical cliff the coyote lands. (c) Determine thecomponents of the coyotes impact velocity.
