In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at x₁ = 0 and the green car is at x = 225 m. If the red car has a constant velocity of 26.0 km/h, the cars pass each other at x = 44.1 m. On the other hand, if the red car has a constant velocity of 52.0 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs. (a) Number i 61.1 (b) Number i -4.05 Red car Unit Unit km/h m/s^2 Green car
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.
In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At time t = 0, the red car is at xr = 0 and the green car is at xg = 225 m. If the red car has a constant velocity of 26.0 km/h, the cars pass each other at x = 44.1 m. On the other hand, if the red car has a constant velocity of 52.0 km/h, they pass each other at x = 76.6 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs.
