1. A train 180 m long is chugging along a railroad track going north. Along another railroad track, very near and parallel to the first, another train 100m long is trying to overtake the first at 180 km/hr. If the first train is running at 120 km/hr and its tail end is exactly 500 m ahead of the front of the second train, then find the following: a. How many meters have the first train traveled when the front end of the second train caught up with its end? b. How many meters have the second train traveled when its front end caught up with the tail end of the first train? c. How many seconds would have elapsed from the initial position when the second train has completely and clearly overtaken the first train?

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.

Question

1. A train 180 m long is chugging along a railroad track going north. Along another
railroad track, very near and parallel to the first, another train 100m long is trying
to overtake the first at 180 km/hr. If the first train is running at 120 km/hr and its tail
end is exactly 500 m ahead of the front of the second train, then find the following:
a. How many meters have the first train traveled when the front end of the
second train caught up with its end?
b. How many meters have the second train traveled when its front end caught
up with the tail end of the first train?
c. How many seconds would have elapsed from the initial position when the
second train has completely and clearly overtaken the first train?

At 10:17 a.m., you pass a police car at 55 mph that is stopped on the freeway. You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.
