I still can't get it I'm thinking about it like aaeba now but it's still wrong in 1 and 2 I think the acceleration would be a because it's both pointing in the negative direction 3 is 0 because it's not moving 4 would be b because it's about to speed up in that direction and 5 is a because it's...

how do i solve it to know which way the acceleration is going

Homework Statement Homework Equations accelerationThe Attempt at a Solution I tried the answer: BAEBB 1 looks like its accelerating up 2 looks like its accelerating down 3 the acceleration looks like it is 0 (v=0) 4 the acceleration looks like its going back up 5 the acceleration looks like...

ohhhhhhhhh ok i got it lol I am an idiot thanks

i don't know for the first one would you subtract 0.7m - 0.525m? and for the second one you would use \lambda = 4L/2n-1 would the answer be 4.25m to 0.00425m? i had both the right answers but i eraced them and i can't tell what the final answer would be for both them
