1) A golf ball is hit from the roof of a single-story building (5 meters above the parking lot below). The ball is given a speed of 12 m/sec at an angle of 35 degrees above the horizontal. (Ignore air resistance.) a) Calculate the total time of flight (until it hits the parking lot below) in seconds. b) Calculate the highest point it reaches (measured from the parking lot), and at what time. c) Calculate magnitude of the speed at 1.5 seconds (and explain why this number is reasonable, relative to the initial speed).
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.
