In an experiment, one of the forces exerted on a proton is F⃗ =−αx2i^, where α=12N/m2. What is the potential-energy function for F⃗ ? Let U=0 when x=0. Express your answer in terms of α and x.

(75°f − 32) × 5/9 = 23.889°c

the total distance traveled by the car is

30km + 49km = 79 km .

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
