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

Answers: T<span>he elastic potential energy can be increased by: </span>
<span>1) Getting a spring with a higher spring constant</span>
<span>2) Increasing the length at which the spring is compressed.
Reasons: Getting a stronger spring makes it stronger which equals more energy. While increasing the compression on the spring, increases the stored energy which makes it more powerful when its released
