Pushing a Cat?. Your cat “Ms.” (mass 7.00 kg) is trying to make it to the top of a friclionless ramp 2.00 m long and inclined upward at 30.0° above the horizontal. Since the poor cat can’t get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 100-N force parallel to the ramp. If Ms. takes a running start so that she is moving at 2.40 m/s at the bottom of the ramp, what is her speed when she reaches the top of the incline? Use the work-energy theorem.

QUESTION:
Pushing a Cat?. Your cat “Ms.” (mass 7.00 kg) is trying to make it to the top of a friclionless ramp 2.00 m long and inclined upward at 30.0° above the horizontal. Since the poor cat can’t get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 100-N force parallel to the ramp. If Ms. takes a running start so that she is moving at 2.40 m/s at the bottom of the ramp, what is her speed when she reaches the top of the incline? Use the work-energy theorem.
ANSWER:Solution 82P Step 1: Mass of the cat is m = 7.0 kg Length of the ramp is L = 2.0 m. 0 Angle of inclination = 30 Force applied is F = 100 N. Speed of the cat at bottom of the ramp is v = 2.40 m/s.
