Statement

1.1.13. From the graph of the dependence of the coordinate on time, graph the dependence of the velocity on time.

For problem 1.1.13

Solution

Two different velocities
Two different velocities

In this periodic motion, two velocity regimes can be distinguished: when the velocity is positive and when it is negative.

Based on the speed definition, the speed in each mode will be and , respectively:
