Your cat Goldie (mass 8.50 kg ) is trying to make it to the top of a frictionless ramp 6.640 m long and inclined 33.0 degree above the horizontal. Since Goldie can't get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 43.70 N force parallel to the ramp (there is a set of stairs alongside the frictionless ramp on which you can walk). If Goldie is moving at 1.650 m/s at the bottom of the ramp (assume she has gotten a running start), what is her speed when she reaches the top of the incline?

What is the cat's speed v_2 when she reaches the top of the incline?
