|(a) If the vector A = 21 + 3j + 8k is perpendicular to the vector B = -4î + 4j + nk, find the value of 'n'. Use the value of n and calculate the vector (cross) product of Ả and B. (b) Tarzan is swimming East at 2.4 m/s across a river that is 1660m wide and flows North at 5.2 m/s. Calculate the magnitude and direction of his resultant velocity.
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.
