If a rock is thrown upward on the planet Mars with a velocity of 11 m/s, its height (in meters) after t seconds is given by H = 11t − 1.86t2. (a) Find the velocity of the rock after one second. ______m/s (b) Find the velocity of the rock when t = a ______m/s (c) When will the rock hit the surface? (Round your answer to one decimal place.) t =________s (d) With what velocity will the rock hit the surface? ______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.
