    A boy is tobogganing down a smooth slope inclined at 20 degrees to the horizontal. Find his acceleration, assuming resistances can be neglected.

    I am really stuck on this question. I know that the answer is 3.35m/s^2 (because we are given an answer sheet) but i dont know how to work it out.

    Draw the force of gravity as two components horizontal and vertical to the slope, and then calculate the answer to the force that is horizontal to the slope.
