3.) A ball is dropped (from rest) from the top of a building at HCC. It travels for 3.0 seconds before it hits the ground below. Assume free-fall occurs (no air resistance). a) How tall is the building? b) How fast is the ball traveling when it hits the ground? c) If the ball was dropped from twice the height, how long will it take to hit the ground?
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 value---
- A ball is dropped (from rest) from the top of a building at HCC. It travels for 3.0 seconds before it hits the ground below.
We have to find---
- a) How tall is the building?
- b) How fast is the ball traveling when it hits the ground?
- c) If the ball was dropped from twice the height, how long will it take to hit the ground?
