An extreme skier, starting from rest, coasts down a mountainthat makes an angle $25.0}^{\circ$ with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.200. She coasts for a distance of 11.9 m before coming to the edge of a cliff. Without slowing down, she skis offthe cliff and lands down hill at a point whose vertical distance is 4.20 m below the edge. How fast is she going just before she lands?

A 2.0- kg piece of wood slides on the surface. The curved sides are perfectly smooth, but the rough horixontal bottom is 30 m long and has a kinetic friction coefficient of 0.20 with the wood. The iece of wood starts fromrest 4.0 m above the rough bottom (a) Where will this wood eventually come to rest? (b) For the motion from the initial release until the piece of wood comes to rest, what is the total amount of work done by friction?

A golfer hits a golf ball at an angle of 25 degrees to the ground. If the golf ball covers a horizontal distance of 301. 5 m, what is the ball's maximum height? (Hint: at the top of its flight, the ball's vertical velocity component will be zero.)

If $x}_{n}=\mathrm{cos}\left\{\sqrt{n+1}\right\}-\mathrm{cos}\left\{\sqrt{n}\right\$ , what is $\underset{x\to \mathrm{\infty}}{lim}{x}_{n}$ ?

I think it may be 0, because$\sqrt{n+1}$ and $\sqrt{n}$ are two very close angles. But I don't know how to prove it. If I use the formula for $\mathrm{cos}-\mathrm{cos}$ , I get $-0\cdot \mathrm{\infty}$

I think it may be 0, because
