9. A toy rocket fired straight up into the air has height s(t) = 320t – 16t? feet after t seconds a) Find the average velocity between the first and fourth second? b) What is the rocket's instantaneous velocity after 3 seconds? c) When does the rocket reach a height of 1024 feet? d) When does the rocket hit the ground? e) What is the rocket's velocity when it hits the ground? (After it launched) f) How high up is the rocket when the rocket reaches a velocity of 16 ft/sec g) Describe the meaning (using units of measurement) for s(1) = 304 h) Describe the meaning (using units of measurement) for s'(12) = -64
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.
