    #1 has several errors. There is no 30 degrees in the problem, and the signs are not correct. The bank is the wrong way for the normal force to be making a positive contribution to the needed centripetal force. It appears the normal force is not what you think it is. You need to draw a free body diagram with all forces resolved into horizontal and vertical components. There is no vertical acceleration, so the sum of the vertical forces must be zero. The sum of the horizontal forces must provide the centripetal acceleration.

    For #2 is the ramp frictionless? I don't see how you have used the block on the ramp. Again you need free body diagrams, one for each block.
