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 11.0 m/s² in the horizontal direction. The roadrunner is moving at a constant speed toward a cliff. The coyote is initially at rest 65.0 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.") ВЕЕР ВЕЕР (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 (11.01 - 9.80ĵ) m/s². (b) The cliff is 100 m above the flat floor of a wide canyon. How far (in m) from the base of the vertical cliff does the coyote land? m (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 m/s
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
