Study of the kinematic characteristics of the motion of the car from the top to the design point by Djabbarov Shukhrat, Saidivaliev Shukhrat, Abdullayev Bakhrom, Gayipov Aziz, Rakhmatov Khamza, Soboleva Irina

“…Objective: to describe the speed of the car at each section of the descent part of the hump using the principles of classical mechanics; to get a generalized model of the speed of movement of the car at the estimated point of the hump, which allows speeding up the process of building graphs and changing the kinematic characteristics of the car’s movement; to present the change in the instantaneous speed of movement of the car along the entire length of the descent part of the hump in the form of a graph of the step function. …”
