An object is dropped from a tower, 153 ft above the ground. The object's height above ground t sec into the fall is s = 153 - 16t2. a. What is the object's velocity, speed, and acceleration at time t? b. About how long does it take the object to hit the ground? c. What is the object's velocity at the moment of impact? The object's velocity at time t is The object's speed at time t is ft / sec. The object's acceleration at time t is | ft/ sec2. (Simplify your answer.) It takes |sec for the object to hit the ground. (Round to the nearest tenth.) The object's velocity at the moment of impact is ft / sec. (Round to the nearest tenth.)
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.
