A particle starts from rest at (r0) = 9m j-hat and moves in the xy-plane with the velocity shown in the figure . The particle passes through a wire hoop located at (r1)=20m i-hat, then continues onward.
The question I'm having trouble with is finding the y-component of velocity at t=4
I think it's v = vi + ay delta t
The Attempt at a Solution
I got -40 (express to only one sig fig) and it was wrong, so I have no idea what to do
Someone please just point me in the direction to go, and not to an older thread
