What is maximum speed with car can safely driven?
The maximum speed of car which can be safely driven along a curve of radius 100 m is 14 m/s. So, the maximum speed of car is 14 m/s.
What is the maximum speed with which a car can round a turn?
Putting the values of the parameters and g= 9.8m/s, we get, v=√μgR=√0.4×9.8×30=√117.6=10.84 . Thus, the maximum velocity that can be attained by the vehicle while making the turn is 10.84 m/s.
Is the result independent of the mass of the car?
The weight of the car is (1050 kg)(9.80 N/kg) = 10290 N. Is this result independent of the mass of the car? Since the mass cancels out, the result is not dependent on the mass.

What is the maximum speed at which a car can turn round a curve of 30m?
68m/s.
Does a heavier car take longer to stop?
The lighter car will stop faster because the lighter car has less energy to dissipate than the heavier one, while the tires more equal limits of friction with the road. That's because tires gain traction non-linearly with vertical load.
Does weight of car affect horsepower?
The "horsepower" is just a measure of the amount of power the engine is capable of producing, which is independent of the weight.
What is the maximum speed?
Maximum speed is the highest rate of speed an athlete can attain. Acceleration refers to velocity, and because velocity has both a magnitude and direction associated with it, acceleration changes when athletes change the magnitude of their motion (how fast they are running), the direction of their motion, or both.
How can speed be calculated?
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
Which of the following has maximum speed?
Speed of light is maximum as only frequency and wavelength of light changes and speed remain constant while air, water and sound do not have constant speed. Light carries photons which helps it to travel faster.
On what factors the maximum safe speed for a car moving on a level circular track depends?
Thus the safe velocity on the unbanked road depends on the coefficient of friction between the road and tyres, the radius of the circular path, and acceleration due to gravity at that place.
Are heavy cars safer?
Overview. A bigger, heavier vehicle provides better crash protection than a smaller, lighter one, assuming no other differences. The longer distance from the front of vehicle to the occupant compartment in larger vehicles offers better protection in frontal crashes.
Do heavier cars go faster?
Adding extra weight to your car will slow acceleration, but won't reduce its top speed. In determining a car's top speed, its engine battles two main forces: rolling resistance and aerodynamic drag.
Does a lighter car go faster?
The amount of energy it takes to move a car from one point to another is highly dependent on the mass, so the lighter the vehicle, the less energy it takes to move it from one place to another. A lighter car is also a faster car.
What car has the best power to weight?
Top 50 Supercars listed by power to weight ratios
| No. | Make | Power to Weight (hp/lb) |
|---|---|---|
| 1 | Hennessey | 55.87 |
| 2 | McLaren | 51.97 |
| 3 | McLaren | 51.74 |
| 4 | SSC | 51.92 |

What is speed with example?
Speed is a way of measuring how quickly something is moving or being done, or something moving fast. An example of speed is a car being driven 45 miles per hour. An example of speed is someone cleaning a room in 10 minutes. An example of speed is how quickly a jaguar runs.
What’s the fastest speed recorded?
763.035 mph The current holder of the Outright World Land Speed Record is ThrustSSC driven by Andy Green, a twin turbofan jet-powered car which achieved 763.035 mph – 1227.985 km/h – over one mile in October 1997. This is the first supersonic record as it exceeded the sound barrier at Mach 1.016.
Which light has maximum speed?
colour red The colour violet travels the slowest, so it is on the bottom and the colour red travels the fastest so it is on the top. Was this answer helpful?
What is the maximum speed of a car on a banked road?
The maximum speed with which a vehicle can negotiate a curved road, which is banked at the angle, θ=tan−1(0.24) is 54 km/hr. If another road is flat and the vehicle has to negotiate a curve with the same maximum speed, coefficient of friction between road and tyre should be. (Radius of both the road is same)
Why heavy cars are slower?
So in case you're still thinking about why braking distances are longer for a heavier car it is simply because the tyre friction is slightly lower because the load is heavier (assuming the same tyres). In racing categories, normally, a minimum weight is imposed for reasons of safety and equality.
Which is the safest vehicle?

Why is a lighter car faster?
The amount of energy it takes to move a car from one point to another is highly dependent on the mass, so the lighter the vehicle, the less energy it takes to move it from one place to another. A lighter car is also a faster car.
Does weight Affect car speed?
Adding extra weight to your car will slow acceleration, but won't reduce its top speed. In determining a car's top speed, its engine battles two main forces: rolling resistance and aerodynamic drag. At very high speeds, air resistance makes up the vast majority of the overall drag on your car.
How fast is 1hp?
horsepower, the common unit of power; i.e., the rate at which work is done. In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.
