A train is initially travelling along a straight track at a steady speed of 30 m s-¹. At time t=0.00 s a signal ahead turns red. It takes the driver 0.60 s to react and apply the brakes. Once the brakes are hit, the train decelerates with a constant acceleration of magnitude 9.0 m s2 until it comes to rest. What is the total distance travelled by the train in the period between the signal turning to red and the train coming to rest? Give your answer by entering a number (correct to an appropriate number of significant figures) in the empty box below. Total distance travelled = m.

Concept explainers

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.
