Plz help plz i'll give brainlist
Sorry for the subject btw

Potential energy is at its maximum value for all 3 images.

Explanation:

Mechanical energy equals kinetic energy plus potential energy. There is zero kinetic energy because the object isn't moving, so mechanical must equal potential. Additionally, all 3 objects are at their highest height and potential equals mgh, so the maximum height gives the maximum potential energy.

the top one will be have tons of energy going down the hill the midlle will have energy going backwards and the bottom will have energy in the arms

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
