Your car gets a flat! you go from 90 kilometers per hour to a stop
in 6 seconds. what is your rate of deceleration? (it's negative)

Explanation:

The acceleration of an object can be found using the equation

where

v is the final velocity of the object

u is the initial velocity of the object

t is the time taken for the velocity to change from u to v

For the car in this problem:

is the initial velocity

v = 0 is the final velocity (the car comes to a stop)

t = 6 is the time interval it takes  for the car to stop

Substituting, we find the deceleration of the car:

where the negative sign indicates that the car is slowing down.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
