(28) In 2010, an advertisement for a particular sports car had the for- mer Formula 1 driver Michael Schumacher perform a stunt with the car. Driving into a tunnel, Schumacher spiraled around its inner surface before driving out of the tunnel, once again at ground level. What should the minimum speed of the car be to safely per- form this stunt, if the 100-m-long tunnel is 6 m in diameter, and Schumacher is seen exiting the tunnel two seconds after the start of the stunt? What is the next higher safe speed? Can any speed higher than the minimum lead to a safe stunt?
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.
