In order to find the magnitude of the acceleration due to gravity on some planet, NASA and the CSA invented a simple device which launches a small metal ball straight up with an initial speed of 11.75 m/s. The device then records the maximum height that the ball reaches before returning to the device. If on the planet, the ball reaches a maximum height of 12.0 m (neglecting air resistance) before returning to the device. What is the magnitude of the acceleration due to gravity on that planet?

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.
