A skier has a horizontal velocity of 104.5 km/h at the end of a ramp, before a horizontal surface (the velocity is where the ramp and ground meet). The snow on both the horizontal surface and the ramp produces a coefficient of friction of .12 with the skis. If the initial velocity with which the skier started is twice the velocity of the final velocity (at the end of the horizontal surface), what distance will the skier travel overall?

I think that I need to divide out the ramp and horizontal surface into two parts, but I don't know what to do after that. Do I use Net Work is equal to change in Kinetic Energy or do I use Work of Friction is equal to Change in Kinetic Energy + Change in Potential Energy?

The skier starts off at the top of the ramp. At the bottom of the ramp, his speed is 104.5 km in the horizontal direction.

The distance I need to find is how far the skier travels from the beginning of the ramp to how ever far he travels across the horiontal surface.

I'm a five-digit number containing each of the five odd digits. I'm not dividible by 5. The 1 is neither next to the 3 nor the 7; the 3 is next to the 5. I neither start with nor end in 9 or 1. The middle digit is not prime or composite. The sum of the first two digits is less than the sum of the last two digits. Who am I?

I'm sure we're all familiar with the classic egg drop experiment - build something so that when you drop an egg from a height, the contraption will make sure that the egg does not crack.

My first thought on this was, "Oh, this'll be easy" before I realized that the restrictions were.

RESTRICTIONS
- No foam
- No bubble wrap
- Must weigh 150 g or less, INCLUDING egg [I believe the egg is around 50 g, so that means the thing I use has to be less than or equal to 100 g]

The problem is, what am I going to make that weights 100 g? In reality, that is a really small amount, I think about 100 pennies equals 100 g.

I know I have to somehow distribute the force evenly around the eggshell, but right now, I'm completely stumped. I think I should also use different-density padding, but I have no idea what I'm going to do.

I'd love any ideas, suggestions, and comments to anyone who's willing to help.

Thank you in advance.

In all the other english speaking countries it is pronounced properly. Is it correct in the U.S. to call Uncle Herbert Uncle Erbert?
It sounds like a very silly affectation.

A bicyclist is coasting straight down a hill at a constant speed. The mass of the rider and bicycle is 80.0 kg, and the hill is inclined at 14.0° with respect to the horizontal. Air resistance opposes the motion of the cyclist. Later, the bicyclist climbs the same hill at the same constant speed. How much force (directed parallel to the hill) must be applied to the bicycle in order for the bicyclist to climb the hill?
