Question 2: A snowboarder starts from rest at the top of a double black diamond hill. As she rides down the slope, GPS coordinates are used to determine her displacement as a function of time given by the image below, where x and t are expressed in feet and seconds, respectively. Determine the displacement, average velocity, average speed and average acceleration for the time period from =2 seconds to =7 seconds. Write your answer in the format (d =ft;v_avg = ft/s; v_sp =, ft/s^2) * %3D - ft/s; a_av = * = 0.5t3 + t2 + 2t
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.
