that a ball is dropped from the upper observation deck of a building, 350 m above the ground. hat is the velocity of the ball after 7 seconds? w fast is the ball traveling when it hits the ground? ON need to find the velocity both when t = 7 and when the ball hits the ground, so it's efficient to start by finding the velocity at a general time t=a. Using the equation of motion = 4.9t, we have the following. lim lim lim f(a+h)-f(a) h 4.9 h 4.9(a² + 2ah+h² h lim 4.9 4.98² =9.8( [ e velocity, in m/s, after 7 seconds is v(7) = ce the observation deck is 350 m above the ground, the ball will hit the ground at the time t, in seconds, when s(t) = 350, that is, we have the following.
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.
