A car starts from a stand still with a constant acceleration of 3.94 ft/ s2 for 20 seconds. At that instant, upon reaching that speed, the driver decides to move at a constant speed for 40 seconds. In the last section of its journey, the driver hits the brakes causing a deceleration of 8.20 ft/s2 until the car comes to a complete stop. Indicate the type of movement that occurs in each section, calculate velocity, acceleration and position in each section (express the results in the International System units), graph velocity, acceleration, and position as a function of time for those same sections, and finally calculate the distance traveled.

Question
A car starts from a stand still with a constant acceleration of 3.94 ft/ s2 for 20 seconds. At that instant, upon reaching that speed, the driver decides to move at a constant speed for 40 seconds. In the last section of its journey, the driver hits the brakes causing a deceleration of 8.20 ft/s2 until the car comes to a complete stop.
Indicate the type of movement that occurs in each section, calculate velocity, acceleration and position in each section (express the results in the International System units), graph velocity, acceleration, and position as a function of time for those same sections, and finally calculate the distance traveled.
