Homework Help: Block on an incline

  1. Feb 6, 2008 #1
    [SOLVED] Block on an incline

    A 11.4-kg block is released from rest on a frictionless track inclined at an angle of 47°. (a) What is the net force on the block after it is released? (b) What is the acceleration of the block? (c) If the block is released from rest, how long will it take for the block to attain a speed of 9 m/s?

    I have been working on this problem but for some reason I must have an error somewhere, can anyone show me the correct answers.
