Plz answer as soon as possible.​

Answer 1

Answer:

hii

Step-by-step explanation:

Given, Speed=18km/h,t=5s

a)The speed of the car in m/s=18×

18

5

=5 m/s

b) The retardation is:

a=

t

v−u

=

5

0−5

=1m/s

c) The velocity of the as a funcition of time 2sis:

v(t)=5−t⇒v(t)=5−2=3m/s=10.8 km/h
