First, we can use an algebraic method. Remembering the equation of motion𝑠=𝑢×𝑡+12×𝑎×𝑡,where𝑠is the object’s displacement,𝑢is its initial velocity,𝑎is its acceleration, and𝑡is the acceleration time, we can substitute in the known values of𝑢,𝑡,and...
A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car and the distance traveled. A car accelerates uniformly from rest to a speed of 40.0 miles per hour in 12.0 seconds. a. Find th...
So for the moment, we will consider variables like displacement , velocity , and acceleration as scalar quantities, although they are VECTORS. The displacement from position to is given by The displacement with respect to the origin of a coordinate system is merely x. We define the average ...

The formula to calculate distance over a period of time is : distance=rate×timedistance=rate×time To give an example of this, if you're traveling 60 miles per hour (mph) and drive for two and a half hours (2.5 h), you can calculate the distance traveled as: distance=60×25=150...
In this paper we have presented a methodology used to determine actual acceleration, velocity and traveled distance profiles of vehicles of different categories in urban environment, as dominant microscopic traffic flow parameters. The tests have been done on representative arterial road in the city of...
The constant acceleration equations use the following symbols: a stands for acceleration, v means final velocity, u means starting velocity, s means displacement (i.e. distance traveled) and t means time. The equations state: ...

Basically you seem to neglect the equation that relates the distance traveled to the time it takes during acceleration or deceleration. It is [itex]s_1=0.5a_1t_1^2[/itex] and [itex]s_2=v_it_2-0.5a_2t_2^2[/itex] where v_i the velocity at the time t1 where acceleration stops...
