19.15 feet is the distance the car travel in that time when a car traveling at 80 feet/sec decelerates at a constant rate so that it comes to a complete stop after 30 seconds.

What is deceleration ?

  • Deceleration is described as a reduction in speed as the body advances away from the beginning position.
  • The opposite term of acceleration is defined as deceleration. It is written as. Also negative acceleration is another name for deceleration.

Solution:

To find the constant deceleration rate we use a = Δv/Δt.

a=80feet/sec/30s

a=-2.66 m/s^2

now to find the distance travelled

s =  80*-2.66 *30^2 =19.15 feet    (where s= distance)

Hence,19.15 feet is the distance the car travel in that time when a car traveling at 80 feet/sec decelerates at a constant rate so that it comes to a complete stop after 30 seconds.
