An air force soldier wants to accelerate from rest at a constant acceleration of 6g to reach Mach 3 as quickly as possible to show off his skills. Studies show that a person will blackout if this acceleration lasts for more than 5.0 s. (Use 331 m/s for the speed of sound.) (a) Will the period of acceleration last long enough to cause him to blackout? (b) What is the greatest speed he can reach with an acceleration of 6g before he blacks out?
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.
