A rock is thrown at a window that is located 18.0 m above the ground at an angle of 40.0° above horizontal angle. The rock is thrown from a height of 2.00m above the ground with a speed of 30.0 m/s with no air resistance. If the rock strikes the window on its upward trajectory, from what horizontal distance from the window was it released? answers: 27.3m, 53.2m, 29.8m, 48.7m, 71.6m ?
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.

Given data
The location of the window from the ground is Sy = 18 m
The rock is thrown at an angle of = 40
The initial speed of the rock is u = 30 m/s
The initial height from where rock is thrown is yo = 2 m
