Your cat "Ms" (mass 7.00kg) is trying to make it to the top ofa frictionaless ramp 2.00 m long and inclined upward at 30 degreesabove the horizontal . since the poor cat cant get any traction onthe ramp, you push her up the entire length of the ramp by exertings constant 100N force parallel to the ramp. If ms. takes a runningstart so that she is moving at 2.40m/s at the bottom of the ramp, what is her speed when she reaches the top of the incline.
