In the figure, a crate of mass *m* = 92 kg is pushed at a constant speed up a frictionless ramp (*θ* = 27°) by a horizontal force F→. The positive direction of an *x* axis is up the ramp, and the positive direction of a *y* axis is perpendicular to the ramp. **(a)** What is the magnitude of F→? **(b)** What is the magnitude of the normal force on the crate?

Step 1

(a)

Since the crate is pushed at a constant speed so that acceleration is zero, the net force acting the crate is F_{net}=0.

Find the expression for the applied force on the crate.

Step 2

Substitute the values,

Step 3

(b)

Find the expression for the magnitude of ...
