A rock is dropped from a bridge to the water below. It takes 5.25 deconds for the rock to hit the water. What is the velocity of the rock as it hits the water in metres per second? How far from the water is the bridge (in units of metres to 3 decimal places)? State at the start of the problem which direction is positive (using the up arrow or down arrow) Make a list of all given values, units, and variables they represent. Write the general form of the equation you are going to use. Insert the known variables and solve.
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.
