A rock is projected upward from the surface of the Moon, at time t = 0 s, with an upward velocity of 35.0 m/s. The acceleration due to gravity at the surface of the Moon is 1.62 m/s², and the Moon has no atmosphere. What is the closest value of the time t when the rock is descending with a speed of 25.0 m/s. 32 s. 22 s. 55 s. 48 s. 37 s.
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.
