Physics, Elena Please Help If u can.
well now that u can see answers I was soooooooo close on the EOM and the angular velocity......ugggg so close.....(the only 2 I missed)

Physics, Elena Please Help If u can.
in one direction its 0, theres no movement

Physics, Elena Please Help If u can.
so u have accel now right just need velocity?

Physics, Elena Please Help If u can.
no close, tho get rid of the 2 for something else and its a - not *

Physics, Elena Please Help If u can.
well heres alittle gift because I know the frustration of not knowing one because of the syntax and being close. this is in j hat direction 2*omega*v-omega^2*L

Physics, Elena Please Help If u can.
o wait u said u don't have second part right? the equation of motion?

Physics, Elena Please Help If u can.
