Kinematics

Suggestion: Convert miles to kilometers, then it should be easy to compare. One mile is about 1.6 kilometers.

From the perspective of an observer inside the vehicle, everything inside it appears to be stationary or moving at the same speed as the vehicle (30 miles per hour) due to inertia. This means that if you were inside the vehicle and not looking outside, you would not feel the motion.

At a speed of 180 mph, it would take approximately 45.45 seconds to travel a quarter mile.

The sign "Exit 25 mph" indicates that drivers should slow down to 25 miles per hour when exiting the road. It serves as a reminder to reduce speed to safely navigate the exit ramp. It is important to follow this posted speed limit for the safety of yourself and other drivers.

The speed of a 212cc engine depends on various factors such as the vehicle it is powering, gearing, weight, and aerodynamics. However, in general, a 212cc engine can reach speeds of around 40-50 mph in a go-kart or similar small vehicle.

Traveling at 60 mph instead of 55 mph will save you around 5 minutes on a 10-mile trip. This is because at 60 mph, you cover 10 miles in 10 minutes, while at 55 mph, it takes around 11 minutes to cover the same distance.

In the US there is no universal set speed based on distance from shore. However, many areas have local restrictions which should be posted. The major concern is endangering swimmers or other boaters. Also, your boat's wake can cause problems for other boaters, swimmers, and damage the bank. Most places where speed is a concern have posted speeds from 4 to 7 knots, but again, regardless of speed, you must be aware of your wake.

The answer depends on its starting speed. If starting from a standstill, it will be travelling at 1/6 mph.

To find the average speed, add up all the speeds and then divide by the number of speeds given.

(45 + 37 + 34 + 40) / 4 = 39 mph.

Therefore, the average speed of the cars is 39 mph.

Mach 1.7 is approximately 2,088 kilometers per hour.

When you stretch a bow , the work done by you in stretching the bow is stored in the form of potential energy . This potential energy get converted in to kinetic energy of the bow when released.

The Razor MX500 Dirt Rocket has a maximum speed of 17 mph.

Break out your calculator or if you're good then grab a pencil and paper. Divide 48 (the miles you rode) by 30 minutes (the speed you rode.) 48 divided by 30 equals 1.6 or 1.6 hours. There are 60 minutes in an hour so now we need to figure out what .6 or 6 tenths of an hour is. 60 divided by 10 is 6. This gives us what one tenth is. We know that we have 6 tenths so 6 times 6 is 36 or 36 minutes. Soooo... It will take you 1 hour and 36 minutes to travel 48 miles on your bicycle. I gave you one method of figuring it out for yourself. Someone once said, "Give a man a fish and you feed him for one day. Teach a man to fish and you feed him for life."

Speed shock refers to the feeling of disorientation, physical discomfort, or psychological distress that can occur when someone travels at high speeds, such as in a vehicle or on a roller coaster. It is a result of the body's sensory systems being overwhelmed by the rapid changes in speed and movement. Symptoms may include nausea, dizziness, or anxiety.

It is 583 miles per hour!

Yes, some trains are capable of reaching speeds of 100 MPH or even greater, depending on the type of train and the infrastructure it operates on. High-speed trains in particular can reach speeds well above 100 MPH on dedicated tracks.

If you could drive non-stop at a constant speed of 60 mph, it would take about 6 hours and 43 minutes.

It is a measure of the average number of miles covered in a period of one hour.

My new answer:

Usain Bolt acheived a top speed of 27.28 mph or43.90 kph in travellng the 2 fastest consecutive 60-70 & 70-80, 10m splits ever of .82 seconds.

We'll leave out 4x100m splits as I don't have them for Team Jamaica's WR from Beijing.

Old answer:

Since Usain Bolt became the 100m WR holder with a 9.68, I don't know if this figure still stands but in the 1996 Atlanta Olympics, Donovan Bailey in a WR time of 9.84 secs, covered a 10m portion at 12.1 meters per second. That would translate to about 27 MPH or about 43 Km/h. Both he and Maurice Greene hit a 10m section of the 100m final of the 1997 World Championships at 11.91 m/s... Greene ran a 9.86 and Bailey ran a 9.91. That would mean both reached a speed of roughly 26.5 MPH. Considering that, even the reductions the WR has taken in the last 12 years, it would be okay to assume 27-28 MPH is the fastest speed ever attained by a person running. Though Bob Hayes, in 1964, ran his leg of the 4x100m relay in 8.50 seconds.

The top speed of a 140cc engine can vary depending on different factors such as the type of vehicle it is installed in, gearing, and aerodynamics. On average, a 140cc engine can reach speeds of around 50-60 mph.

The top speed of a PowersportMax 125cc ATV can vary depending on factors such as the terrain, weight of the rider, and maintenance of the vehicle. On average, a 125cc ATV can reach speeds of around 35-45 mph.

Typically, you should use gears 3 or 4 for speeds in the range of 15 to 25 mph on flat terrain. These gears provide a good balance between pedal effort and speed. Adjust based on your comfort and the terrain.

It would take 6.3 hours to travel 409 miles at a speed of 65 miles per hour (409 miles / 65 miles per hour = 6.3 hours).
