Kilauea volcano in Hawaii is the world's most active volcano. It has a height of 1200 m. While erupting, it shoots out a boulder directly upward at 45 m/s. Part A What is the velocity of the boulder when it reaches the height of the volcano on the way down?
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.

v Correct
This is true for any object in free fall. In the absense of air resistance, an object will always have the same speed when it reaches the same location. The
willbe different though. Hence the same magnitude, but opposite sign.
Part B
How much time does it take the boulder to reach the ground?
