The coyote starts at rest 60.0 m from the edge of a cliff at the instant the roadrunner zips past him in the direction of the cliff.

(a) Determine the minimum constant speed the roadrunner must have to reach the cliff before the coyote.

At the edge of the cliff, the roadrunner escapes by making a sudden turn, while the coyote continues straight ahead. The coyote's skates remain horizontal and continue to operate while he is in flight, so his acceleration while in the air is

Explanation / Answer

Vx=Vxi+Ax(t)===> [Vxi from part A. and Ax=given and (t) from part B.]

Vy=Vyi+Ay(t)===> [Vyi=0 and Ay=-g and (t) from part B.]
