A ball kicked from ground level at an initial velocity of 68 m/s and an angle θ with ground reaches a horizontal distance of 295 meters. What is the size of angle θ and what is time of flight of the ball? a. θ = 17.223⁰, t = 8.44 s b. θ = 19.372⁰, t = 4.6 s c. θ = 18.263⁰, t = 9.3 s d. θ = 16.273⁰, t = 7.3 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.
