A crate of mass m = 1.27 kg is on a frictionless incline that makes an angle of θ = 29.3 degrees with horizontal. A force of magnitude P = 9.45 N is applied to the crate in a direction parallel and up the incline, as shown.
a. Write an expression for the acceleration ax 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/s2).
b. What is the acceleration of the crate in m/s2 in the x direction defined in part (a)?
c. What is the direction of the net force on the crate?
d. What is the direction of the velocity of the crate?
