1. A person standing over an atrium 23.5 m below them and tosses a baseball straight up at 22.1 m/s. The ball lands on the glass of the atrium ceiling and cracks it. Ten seconds later, the ceiling cracks and the ball falls 11.1 m and lands on the floor of the atrium. a) What was the velocity of the baseball just before it hit the glass ceiling of the atrium? b) How long did it take for the ball to hit the atrium ceiling? c) How long does it take for the baseball to fal
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.
11. A person standing over an atrium 23.5 m below them and tosses a baseball straight up at
22.1 m/s. The ball lands on the glass of the atrium ceiling and cracks it. Ten seconds later, the
ceiling cracks and the ball falls 11.1 m and lands on the floor of the atrium.
a) What was the velocity of the baseball just before it hit the glass ceiling of the
atrium?
b) How long did it take for the ball to hit the atrium ceiling?
c) How long does it take for the baseball to fall from the atrium ceiling and hit the
floor?
