A ball is thrown upward from the top of a 6 feet tall platform. The ball is 30 feet off the ground after 1 second and 22 feet off the ground after 2 seconds. The height h above ground is a quadratic function of the time t after the ball is thrown. a) What is the equation that fits this model? b) How long after the ball is thrown will it reach its maximum height? 2 decimals c) What is the maximum height the ball reaches? Answer Answer Answer
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.

2. A ball is thrown upward from the top of a 6 feet tall platform. The ball is 30 feet off the ground after 1 second and 22 feet off the
ground after 2 seconds. The height h above ground is a quadratic function of the time t after the ball is thrown.
a) What is the equation that fits this model?
b) How long after the ball is thrown will it reach its maximum height? 2 decimals
c) What is the maximum height the ball reaches?
