1. A constant horizontal force is applied to a crate of mass m =4.00 kg so that it slides up a frictionless ramp at a constant speed. The ramp makes

an angle 0 = 30.0° with respect to horizontal. (a) [5] On the left, draw a magnitude free body diagram for the crate. On the right,draw a resolved free body diagram for the crate with the +x direction parallel to, and up the ramp, and the +y direction perpendicular to, and away from the ramp. (b) [5] Calculate the magnitude of the applied force. Give a numerical answer.
