To go fast, I needed to minimize the surface area of skin and suit making contact with the slide. Basic speed-chuting position involves crossing your ankles, tensing your core, and arching your back so that there are only three points of contact with the slide: the shoulder blades and a single heel.

So if a skydiver wants to catch up to his fellow skydiver, he can do that by decreasing his A value. One way to do that is to re-orient your body so that your head is facing down. The final drag force the skydiver must experience is from releasing his parachute, which slows his descent enough for him to land safely.

A: How fast something falls due to gravity is determined by a number known as the “acceleration of gravity”, which is 9.81 m/s^2 at the surface of our Earth. Basically this means that in one second, any object’s downward velocity will increase by 9.81 m/s because of gravity.

The mass component of friction cancels out the mass component from the force of gravity. With no friction, mass doesn’t cancel out, so heavier people end up going faster.

40mph downhill is not particularly fast or dangerous on a bicycle.

Many beginning road cyclists ride at average speeds between 10 and 14 mph on the road. Professional bicycle racers can usually maintain 25-28 mph on flat ground. But for a beginning road cyclist, an average of 13.5 mph is very respectable, especially on a longer ride.

More expensive bikes generally have components that work a little better, are easier to maintain, adjust and stay in adjustment better, are lighter and more durable. They are not “faster” just because they cost more.

So, here is our list of best road bikes for beginners:

• Tommaso Imola – Best for the money.
• Co-op Cycles ARD 1.2 – Best for a little extra.
• Raleigh Merit 2– Basic, but well-thought model from good manufacturer.
• Diamondback Century 2 – Runner-up.
• Giordano Libero 2.0 – Solid bike, with good choice of components.

Cruiser Bicycles are similar to hybrid bikes, in that they are designed for casual riding, and have a very comfortable, upright riding position, and a large, comfortable seat. Cruisers usually have wide “balloon” tires, and handlebars that are even more upright, and in some cases, swept back compared to hybrid bikes.

Cannondale offer their riders the opportunity to fall in love with an extremely well-designed and well-built machine. If you’re looking for something more traditional, then maybe Trek is the better choice for you. With a greater range of models and prices, Trek truly offers something for everyone.
