A 20 kg mass is allowed to accelerate down a frictionless 15° ramp.
a. Determine the value of the x-component of the force gravity.
b. What is the acceleration of the block down the ramp.
c. How long will it take for the block to slide 30.0m?

    a) zero. Gravity acts downward. That is usually called the y direction. The Force component DOWN the ramp is
    M g sin 15.
    What are they calling the x direction?
    b) a = g sin15 = 2.54 m/s^2
    c) t = sqrt(2L/a) = 4.86 s
