What kind of speed is registered by an automobile speedometer?

The speed increase is due to the “coefficient of friction” which refers to how much surface area you can transfer in one direction. for example, when you are driving your car at 30 mph on concrete, only 4 square inches of contact between the tire and the surface (the equivalent of a 16×16 inch square) is made. when driving on ice (which has 0 units for coefficient-of-friction), there's no contact between rubber and ice; thus it's difficult or impossible to move at all.

the principle reason an automobile speedometer displays different readings than what meters measure is because meters measure pressure differential across their surfaces whereas automobiles use rolling circumference (2πr). as shown in the graph below, the

what speed is registered by an automobile speedometer?

most us-spec automobile speedometers measure mile/h on the left side, with kilometer/h on the right side.
the answer given is wrong. km/h is placed on the left while mph is placed on the right!

this makes sense, considering that most of europe drives on the right side of the road and mph would be read in reverse (mph) if displayed approaching head-on (coming from right to left). so it's better to give credence to kilometres since they are more important in europe. hmph.. what were you thinking? *facepalm*

one can often tell if one is driving slower than 105 km by leaving 2 lanes of space between their

what is the acceleration of a car moving along a straight road that increases its speed from 0 to 100 km/h in 10 s?

the acceleration of a car moving along a straight road that increases in i is constant, always following the rule that curve of velocity is proportional to the radius on which it is traveling.

the more centrifugal force acting on an object, the higher its acceleration will be on its descending side on earth–this means there are two forces at work for cars approaching curves. these are gravity which equates to 9.8m/s^2 and centripetal forces increasing in relation to increasing curvature while pulling towards the center of rotation. cars approach their left side with increased centripetal force while decreasing gravity–so when you're rounding a corner your right foot's gas pedal still controls your speed even if your accelerator isn

what is the average speed in kilometers per hour for a horse that gallops a distance of15 km in a time of 30 min?

galloping at a steady 40km/h is an average speed for a horse.
the most common measurements on the distance of the gallop comes from both horses and riders who count steps on firm, level ground. one such measurement is 14.32 strides per second or 203 meters per minute (or 736 meters per hour). holding this pace on an even, hard surface will result in 31 km/h or 18 mph – but this isn't taking into account jockeys and their paraphernalia! the more people and equipment you add to your moving herd, the slower they go. this means that it's estimated that only about 8 miles can be covered in one day of work without wearing out everyone involved –

what exactly is meant by a freely falling object?

a freely falling object is the result of gravitational forces. these forces, which come into play when you look at things like terminal velocity or water droplets slowly dispersing in the sky, are what cause objects to fall towards earth. it's worth noting that while these forces can be felt on earth (and sometimes provide an uncomfortable feeling when there's been a prolonged earthquake), they're most often not perceptible in day-to-day life unless you're looking for them.
