Solution

The graphs of the coordinate dependence on time is plotted for two particles using two different time
scales. The plotted graphs turn out to be the same. One division of the time axis
$t$ for the graph of the first particle corresponds to $4 \text{s}$, and for the graph of the
second particle is $1 \text{s}$. Find the ratio of velocities and the ratio of particle accelerations
for point A of the graph.
