Q4// Two cars A and B, approaching each other in adjacent highway lanes. A and B are 0.8 mi apart at t=0, and their speed are 70 mi/h and 40 mi/h respectively when they at P and Q position. Knowing that car A passes point Q 38 s after B was there and that B passes point P 42 s after A was there. Determined : a) The uniform *. acceleration of A
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.

Q4// Two cars A and B,
approaching each other in
adjacent highway lanes. A and B
are 0.8 mi apart at t=0, and their
speed are 70 mi/h and 40 mi/h
respectively when they at P and
Q position. Knowing that car A
passes point Q 38 s after B was
there and that B passes point P
42 s after A was there.
Determined : a) The uniform
