Explanation Given: Acceleration of the car, a = 1.8 m/s 2 Initial velocity, v i = 65 km/h Final velocity, v f = 120 km/h Formula Used: The time can be found from the first equation of motion: v f = v i + a t Calculation: First,convert 65 km/h and 120 km/h to m/s. 65 km/h= 65×1000 60×60 =18

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, fo…

Required information Two speakers vibrate in phase with each other at 523 Hz. At certain points in the room, the sound waves from the two speakers interfere destructively. One such point is 1.45 m from speaker #1 and is between 2.00 m and 4.00 m from speaker #2. The speed of sound in air is 343 m/s. How far is this point from speaker #2? m
