Directions: Show your complete solutions for the following worded problems. 1. A flower pot falls a window of a three-storey apartment. How far has it fallen after 2 seconds? What is the pot's velocity after I s of fall? after 2 seconds of fall? 2. A brick falls freely from a high scaffold and hits the ground after 3.5 seconds. How high is the scaffold? What is the velocity of the brick just before hitting the ground? 3. Alice thrown a ball upwards vertically from the roof of a building. The ball leaves her hand at a point level with the roof railing with an upward speed of 15 m/s. On its way back down, it just misses the railing. Find (a) the ball's position and velocity 1.0 s and 4.0 s after leaving her hand; (b) the ball's velocity when it is 5.0 m above the railing; (c) the maximum height reached.
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.
