A rocket-powered hockey puck moves on a horizontal frictionless table. The figure below shows the graphs of vz and vy, the x- and y-components of the puck's velocity. The puck start at the origin. v, (cm/s) v, (cm/s) 40 40 - 30 30 20 20 - 10- 10 - Ft(s) 0- -t (s) 1 2 3 4 1 2 3 4. You may want to review (Pages 81 - 85). Part A In which direction is the puck moving at t =1 s ? Give your answer as an angle from the x-axis. Express your answer using two significant figures.
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.
