I need to drive from A to C via B at total distance of ΔL. The distance from A to B is ΔL1, from B to C is ΔL2. I have time Δt to get from A to C, so I figure I can make it if I average = ΔL/Δt for the entire trip. Going from A to B, the traffic is heavy and I can only average a speed v1. How fast do I have to go from B to C in order to average for the whole trip? Write an equation expressing v2 (the speed I need to average going from B to C) in terms of the other symbols given: v1, ΔL1, ΔL2, and Δt.
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.
I need to drive from A to C via B at total distance of ΔL. The distance from A to B is ΔL1, from B to C is ΔL2. I have time Δt to get from A to C, so I figure I can make it if I average <v> = ΔL/Δt for the entire trip. Going from A to B, the traffic is heavy and I can only average a speed v1. How fast do I have to go from B to C in order to average <v> for the whole trip? Write an equation expressing v2 (the speed I need to average going from B to C) in terms of the other symbols given: v1, ΔL1, ΔL2, and Δt.
