A crate of mass m = 1.12 kg is on a frictionless incline that makes an angle of θ = 27.6 degrees with horizontal. A force of magnitude P = 7.24 N is applied to the crate in a direction parallel and up the incline, as shown.
Write an expression for the acceleration a_{x} of the crate, where positive x is up the incline. Your answer should be in terms of m, P, θ, and g (9.80 m/s^{2}).
