Answer:

please mark brainlist

Explanation:

Initial speed   u=80 km/h=80×185=22.22 m/s

Final speed    v=60 km/h=60×185=16.67 m/s

Using   v=u+at

Or   16.67=22.22+α×5

⟹ a=−1.1 m/s2

Alborosie

Answer:

K=100.62N/m

Explanation:

Given:

             m= 8.0 Kg\\x=0.78 m

We know from Hook's law

           F= k x

where

           F= m g

So equating we get

             mg=kx\\k=\frac{mg}{x} \\k=\frac{8*9.8}{0.78}\\k=100.62 N/m
