A person holding a ball is on top of a building. The person jumped at the rate of 1 ft/s while dropping the ball. After 12 seconds, the ball hit the ground. Determine the following: a. The initial velocity of the ball; b. The time to reach the maximum height of the ball with reference to the ball's starting point; Ignore the dimensions of the ball and the height of the person. Use g = –32 ft/s². Give exact answer i.e., do not round off answers.
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.
