i made this cylinder, and put four fins on the top of it, and it is supposed to go straight down, but one of my fins is bent a bit, and it causes the vehicle to spin as it falls down, and i was curious on why it does that

Do fins help an object rotate? example, a nerf football

hey, how would you find the minimum speed of an object required to make it go around a circular loop?

wait, i got it, thanks everyone, i now used Ugo=Uef+Ugf

in the intial situations, there is only intial elastic potential then for the final, there is final elastic and final gravitational. what value should i use for the height for the gravitational value?

im pretty sure it is, becuase the problem before it needed that height to calculate the velocity at equillibrium, and i got that

i found out that when the object is in equllibrium, the spring goes displaces 4.9 m using mg=k(l-L) where k is 100 and the mass is 50

oh my bad, its asking what is the maximum compression of the spring

Homework Statement A 50-kg mass is dropped from a 20-m height onto a very long, initially uncompressed spring of force constant k = 100 N/m Homework Equations Ueo=Ugf+Uef F=k(Lenght Final-length initial) The Attempt at a Solution I tried using Ueo=Ugf+Uef, and i couldn't...
