The determined coyote is out once more in pursuit of the elusive roadrunner. The coyote wears a pair of Acme jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2 (Fig. P4.65). The coyote starts at rest 55.0 m from the brink of a cliff at the instant the roadrunner zips past him in the direction of the cliff. The roadrunner moves with constant speed. Determine the minimum speed he must have so as to reach the cliff before the coyote.
