Question

In a scene from a classic cartoon, a hungry coyote is chasing a roadrunner, as shown in the figure below. To aid in his quest, he has donned a pair of ACME brand rocket-propelled roller skates. The skates accelerate the coyote at 14.0 m/s n the horizontal direction. The roadrunner is moving at a constant speed toward a cliff. The coyote is initially at rest 30.0 m from the cliff at the instant the roadrunner moves past him. (In all questions below, assume right is the positive x-direction and up is the positive y-direction. Also assume you can apply real-world physics principles, as opposed to "cartoon physics.") BEEP BEEP (a) What minimum constant speed (in m/s) must the roadrunner have to reach the cliff before the coyote does? m/s The roadrunner suddenly turns at the edge of the cliff, 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 (14.01-9.80j) m/s2. Problem continues in next problem with new numbers. Solve this part algebraically first to (b) The cliff is 100 m above the flat floor of a wide canyon. How far (in m) from the base of the make it easier to do next problem vertical cliff does the coyote land? (c) What are the components of the coyote's velocity (in m/s) just before he hits the ground? (Indicate the direction with the signs of your answers.) -m/s
