2.) A 5 kg cat on a 2 kg skateboard starts at rest at the top of a 3 m tall ramp. The cat goes down the ramp, then across a rough horizontal surface 2 m long. The friction between the skateboard and the rough surface acts to dissipate 100 J of energy. What is the cat's speed after going over the rough surface? Solve this problem two ways: ((a) First find the cat's speed at the bottom of the ramp (assume no energy is dissipated while traveling down the ramp), then find the cat's speed at the end of the rough surface. This makes it a two-step problem, where you analyze energy conservation twice: first along the ramp, and then along the rough surface. (b) Find the cat's speed at the end of the rough surface directly: apply energy conservation where the "initial" state is the cat at the top of the ramp, and the "final" state is the cat at the end of the rough surface. alidog down a 3m long ramn inclined at 30°.
