Answer 1

Answer:

20km/h........

Explanation:

hope it help you

Answer 2

Answer:

Plz mark me as brainliest.

Explanation:

U= initial velocity= 80 km/h = 22.2 m/s

v= final velocity = 60 km/h = 16.7 m/s

t= time = 5 s

a= acceleration = ?

a=v-u/t

a= 16.7-22.2/5

a= -5.5/5

Therefore, a=-1.1 m/s^2
