No. 1. You forgot to multiply by the constant a. 2. The derivative of sin is cos, not cos. Try again! :)

Nope. Again: 1. You need to write it as a vector. 2. You forgot the a on the ycomponent (jhat). Try again! Don't get discouraged. This takes time to fully understand. ;)

Try writing it as (at  a sin t, a  a cos t). It makes it easier for me. Try that for yourself!
