You throw a ball vertically upward from a 50 - m building roof. The ball left your hand at a velocity of 20.0 m/s. On its way down, it just misses the roof. Ignoring air resistance so that the ball is in free fall, The maximum height reached by the ball is The time needed to reach the maximum height is The time needed for the ball to reach the ground is The final velocity of the ball is Answer is 2 decimal places.
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.
