On level ground a shell is fired with an initial velocity of 30.0 m/sm/s at 70.0 ∘∘ above the horizontal and feels no appreciable air resistance 1. Find the horizontal and vertical components of the shell's initial velocity. Express your answers in meters per second separated by a comma. 2. How long does it take the shell to reach its highest point? Express your answer with the appropriate units. 3. Find its maximum height above the ground. Express your answer with the appropriate units.
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.
