The 101-lb crate is carefully placed with zero velocity on the incline. What is the acceleration of the block (positive down the incline) if (a) ̘ = 13 and (b) ̘ = 21?

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?
