Distance is a 1-dimensional phenomenon. its unit is a meter(m). The distance can be found by the product of velocity and time.
The given data in the problem will be
u is the initial velocity =20m/sec
t is the time =?
d is the distance =?
From the Newtons second law;
The distance travelled before the car stop is,
Hence,the time taken, and the distance travelled by the car before stop, will be 5.3 second and -53.3 m west.
