An aging coyote cannot run fast enough to catch a roadrunner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 14.0 m/s2 (see figure). The coyote starts at rest 50.0 m from the edge of a cliff at the instant the roadrunner zips past him in the direction of the cliff. Determine the minimum speed the roadrunner must have to reach the cliff before the coyote.
