What is the speed of a moving car is 20 m per second?

⇒72 km h−1.

What is the coefficient of a car moving with a speed of 20m s?

A motor car is moving on a straight horizontal road with a speed of 20 m/s. The coefficient of friction between the tyres and the road is 0.4. The minimum distance in which the car can come to stop is: 50 m.

What is 20m in 5 seconds?

speed = 20 meters / 5 seconds = 4 meters per second.

What if a car travels 20 meters in a second?

The average speed of a car is 20 meters per second. 72 km/hr.

What is the acceleration of a car moving at a constant velocity of 30m s?

A car is moving at a constant speed of 30 m/s in a straight line. The acceleration of the car is zero.

What is speed coefficient?

The ratio of the maximum fluctuation of speed to the mean speed is called the coefficient of fluctuation of speed. The reciprocal of the coefficient of fluctuation of speed is known as the coefficient of steadiness.

What is speed friction coefficient?

Coefficient of friction (COF) is a dimensionless number that is defined as the ratio between friction force and normal force (Eqn (2.1)). Materials with COF smaller than 0.1 are considered lubricous materials. COF depends on the nature of the materials and surface roughness.

What is 100 m in 20 seconds?

To answer this question, we will need the following equation: SPEED = DISTANCE/TIME (A multiplication and division triangle will be shown)i) The speed of the car is calculated by doing 100 metres/ 20 seconds which gives us 5 metres per second.

How to find velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

How many cars is 20m?

If you want to do your own number plate test, when walking down a street or in a car park, 20 metres is about 5 car lengths.

When a car travels 20 km in 20 minutes?

Expert-Verified Answer So if car travel need to travel 20 km in 20 min i.e 1/3 hr so it must be move with speed 60 km/hr.

What speed is the 2 second rule?

For instance, if you are traveling at a speed of less than 35 mph, you should be safe with a two-second cushion. If your speed increases to 35-to-45 mph, a three-second following distance should be safe, while a four-second distance would apply if you were going 46 to 70 mph.

What is the speed if the distance of 200 m is covered in 20 seconds?

Expert-Verified Answer speed = 10 m/sec. The speed is equal to 10 m/sec.

What is the average speed of an object travels 20 m into second and then another 16 m into second?

Hence, average speed of the object is 9 m/s.

How do you calculate car speed per second?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

What is the velocity of a car is 18 meters per second?

Thus, the speed of the car is 64.8 km/hr.

What is the average speed of an object that travels 20 m 5 second and then another 40 minutes 5 second?

The average speed of the object is 6m/s.
