Question

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 24.0 m/s2 (see figure). The coyote starts at rest 65.0 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 speed the roadrunner must have to reach the cliff before the coyote.

m/s

(b) The cliff is 100 m above the flat floor of a wide canyon. Determine how far from the base of the vertical cliff the coyote lands.
m

(c) Determine the components of the coyote's impact velocity. (Assume right is the positive x direction and up is the positive y direction.)

Explanation / Answer

a) First determine how long it will take coyote to reach the cliff. Use the equation relating distance, time, and acceleration (when starting from rest):
d =
