A car skidded to a stop, leaving tire marks on the road that were 250 m long. If the tires slowed the car down at a rate of -3.5 m/s2, what was the initial velocity of the car?​

Respuesta :

Answer:

The given equation tells the relationship between the velocity and the length of skid mark,so simply by putting the given values,we can determine the length of the skid mark.

Given,

v

=

25

miles/ hrs=

25

(

i.e

36.67

f

=

0.5

So,from the equation,we get the length of the skid mark=

d

=
