1. Two kayakers move along the same straight line. The first one starts from the place marked START and swims for the first 25 seconds at a speed of 3 m/s, and then at a speed of 2 m/s. The second kayaker swims at a speed of 3.5 m/s, but starts from a point 15 meters away from START and 16 seconds later than the first athlete's start. Count where and when, counting from the start point, the kayakers will meet. START (21 -15 m₂ m 2. A ball of plasticine with a mass of 10 kg, moving at a speed of 10 m/s, hits a stationary cart, which has a mass of 0.4 kg, and sticks to it. Calculate the time after which the cart with the plasticine ball will stop and the distance it will cover. Assume that the coefficient of friction of the trolley wheels on the ground is 0.25. m, v m₁ x (m) m₂

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.
