A cannon ball is launched into the air with an upward velocity of 336 feet per second, from a 14-foot tall cannon. The height hh of the cannon ball after tt seconds can be found using the equation h=−16t2+336t+14h=-16t2+336t+14. A) What was the initial height of the cannon ball? feet B) How many seconds will it take for the cannon ball to hit the ground? seconds {Round to 3 decimal place.
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.
