To practice Problem-Solving Strategy 6.1 Work and Kinetic Energy.

Your cat �Ms.� (mass 7.00kg ) is trying to make it to the top of a frictionless ramp 2.00m long and inclined 19.0? 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 44.0N force parallel to the ramp. If Ms. is moving at 1.80m/s at the bottom of the ramp, what is her speed when she reaches the top of the incline?

A) What is the cat's speed v2 when she reaches the top of the incline?

B)This problem can also be done without the work�energy theorem.

Since the forces acting on the cat are constant, the cat is moving up the ramp with a constant acceleration. Therefore, if you know her acceleration, you can use the equations of motion for constant acceleration to find her final speed. Use Newton's 2nd law to find the magnitude a of the cat's acceleration

Express your answer in meters per second squared to three significant figures.
