person who is 1.2 m tall throws a ball with a speed of 12 m/s at an angle of 44 degrees above the horizontal, as shown in the diagram below. h = 1.2 m, v = 12 m/s, 8 = 44 degrees Use the acceleration due to gravity as g = 10 m/s². What are the x and y components of the ball's velocity the instant before it hits the ground? ) m/s What is the ball's speed (the magnitude of the velocity) the instant before it hits the ground? m/s What is the time of flight; that is, the time taken for the ball to hit the ground after it has left the person's hand?
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.
