A body travels at an initial speed of 1.5 m/s. given a constant acceleration of 0.2 m/s², 6.5 m/sec is the speed of the body at time 25 seconds later.
The word "kinematic" comes from A.M. Ampère's "cinematique," which he created from the Greek "v" kinema ("movement, motion"), which was derived from "kinein" ("to move").
A collection of equations known as the kinematic equations is used to describe how an item moves while its acceleration is constant. Integrals, derivatives, and rates of change must all be understood in order to solve kinematics problems.
The formula v = u + at, where u is the starting velocity and an is the acceleration, is used to calculate the velocity of a particle travelling at a constant speed.
Use the kinematic equation:
v = u + at
or, v = 1.5 + [(0.2)×(25)]
or, v = 6.5 m/s
