- An aging coyote cannot run fast enough to catch a road-runner. He purchases on eBay a set of jet-powered roller skates, which provide a constant horizontal acceleration of 15.0 m/s2 (Fig. P1.78). The coyote starts at rest 70.0 in from the edge of a cliff at the instant the roadrunner zips past 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 coyotes skates remain horizontal and continue to operate while he is in flight, so his acceleration while in the air ss (15.0 - 9.80j) m/s2, (b) The cliff is 100 m above the flat floor of the desert. Determine how far from the base of the vertical cliff the coyote lands, (c) Determine the components of the coyotes impact velocity.arrow_forwardA spittlebug called the froghopper (Philaenus spumarius) is believed to be the best jumper in the animal world.

The jeepney driver sees the traffic light turn red, so he accelerates at -2.50 m/s2, and then let his jeepney come to rest. The jeepney is at rest for 50.0 s, and then accelerates at 2.50 m/s2 to go back to a speed of 30.0 m/s.
