Problem 78

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 15.0 m/s2 (Fig. P4.78). The coyote starts at rest 70.0 m 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 is 115.0i ^ 2 9.80j ^2 m/s 2 . (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.

Step-by-Step Solution:
Step 1 of 3

Motion simply is the change of a physical body’s position with time. There are 4 fundamental types of motion which are:  Linear motion­Example, A skateboarder moving along a straight line.  Circular motion­This involves motion along a circular trail. Example, walking round a circular fountain.  Projectile motion­It involves launching an object in air and the then it coming back down due to the law gravity. It always forms a curved path. Example, shotput, javelin or shooting an arrow in the air  Rotational motion: it involves motion of a stiff body rotating about its axis. Example, a ball spinning on the ground about its axis. The first three motion listed above are all called translational motion. This is because they mov
