2. A ball is thrown from the roof of a 100-foot building with an initial velocity vector of 30i + 40j. Assuming that the only force acting on the ball is gravity, (a) what is the speed of the ball four seconds after it is thrown? (b) what is the maximum height that the ball reaches? (c) how far from the base of the building does the ball land?
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.
