1. A bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane 18.03m long. The bowler hears the ball hitting the pins 3.66s after the ball is released from his hands. What is the velocity of the ball? (speed of sound is 343 m/s) 2. Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 3.85m/s up into the air, how fast will it be moving at a height of 46.07cm? How much time has elapsed upon reaching this height? 3. A skydiver jumped out of a plane to shoot a skydiving scene for a certain spy movie. At what point in time should this spy-wannabe open his parachute when he is aware that the plane was at the altitude of 3871.29m, and he needs to open it at a height of 479.26m?
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.
