2.75 .0. Look Out Below. Sam heaves a 16 lb shot straight up, giv- ng it a constant upward acceleration from rest of 35.0 m/s- for 64.0 cm. He releases it 2.20 m above the ground. Ignore air resistance. (a) What s the speed of the shot when Sam releases it? (b) How high above the ground does it go? (c) How much time does he have to get out of its way efore it returns to the height of the top of his head, 1.83 m above the round?
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.
