Standing at the edge of a cliff 30.5 m high,you drop a ball. Later, you throw a second ball downward with aninitial speed of 11.2 m>s. (a) Which ball has the greater increase inspeed when it reaches the base of the cliff, or do both balls speedup by the same amount? (b) Verify your answer to part (a) with acalculation.
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.

you drop a ball. Later, you throw a second ball downward with an
initial speed of 11.2 m>s. (a) Which ball has the greater increase in
speed when it reaches the base of the cliff, or do both balls speed
up by the same amount? (b) Verify your answer to part (a) with a
