Can a bus moving with a speed of 72 km h can be stopped by brakes after atleast 10m?

Can a bus moving with a speed of 72 km h can be stopped by brakes after atleast 10m?

10.0 4 A bus is moving with a speed 72 km/h can be stopped by brakes after atleast 10 m. What will be the minimum stopping distance, if the same bus is moving at a speed of 144 km/h? [Ans. 40 m]

How much acceleration produced by a bus moving with a velocity of 72Km hr to stop at a distance of 50m?

Hence, acceleration of bus is -4 m/s² and distance travelled by bus after applying brakes is 50 m.

What is the speed of a car moving at a speed of 72 km h?

72Km/hr = 72×5/18 = 20 m/s.

What is a car moving with 72 km per hour convert speed in meters per second?

The correct answer is 20 m/s. 72 Km/hr = 72 x 1000/3600 = 20 m/s. So the converted velocity is 20 m/s.

What distance will be covered by a bus moving at 72 kmph in 30 seconds?

Distance covered by the bus is 600 m.

When a bus was moving with a speed of 54 km h on applying brakes it stopped in?

On applying brakes , it stopped in 8 seconds .

When a car is moving with a velocity of 72 km h its velocity is reduced to 36 km h?

Its velocity is reduced to 36 km/h after covering a distance of 200 m. Calculate retardation in cm/s^2. If the same retardation iscontinued, what further distance does the car move before coming to rest? Ans: 75 cm/s^2 ,66.67 m.

What is the formula for acceleration velocity over time?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

What is acceleration when a bus increases its speed from 54 km h to 72 km h in 5 s?

The correct answer is 1 m/s2. Given initial speed (u) = 54 km/h, maximum speed (v) = 72 km/h. time (t) = 5 seconds. Acceleration = (20-15) / 5 = 1m/s2.

What is the speed formula for vehicle?

The formula for speed and distance is the same for a car as any other object: distance ÷ time. So if you want to calculate the speed of a car at sixty miles an hour, the math is (60 x 5280) ÷ (60 x 60) = 88 feet per second.

What is the diameter of a car moving with a speed of 72?

The diameter of its wheels is 50 cm.

What is the speed of a car moving at 50 km per hour returns on the same route with a speed of 40km hr?

Average speed=1+1(1/50)+(1/40)=44.44m/s.

What is the formula for speed distance time conversion?

That is speed = distance ÷ time. Or to put it another way distance divided by speed will give you the time. Provided you know two of the inputs you can work out the third. For example if a car travels for 2 hours and covers 120 miles we can work out speed as 120 ÷ 2 = 60 miles per hour.

What is a car moving with a speed of 72 km h is brought to rest in 10 seconds by applying brakes?

Answer: The retardation is 2m/s² and the distance traveled by a car after applying brakes is 100m.

What is the speed of a car moving with speed 100 km per hour?

A kilometer has 1,000 meters, and an hour has 3,600 seconds, so 100 kilometers per hour is: 100 x 1,000 / 3,600 = 27.777… m/s.

When a moving bus applies brakes to stop?

When a moving bus breaks to a stop we fall in the forward direction due to inertia of motion and when the bus accelerates from rest, we fall in the backward direction due to inertia of rest.

What is the powerful brake on a bus?

Explanation: The most powerful and effective brake on the vehicle is the service brake, and this should be used in normal circumstances. Well-maintained brakes should apply an even pressure to all the wheels, providing an efficient, controlled stop.

Can an automobile Travelling with a speed of 60 km h brake to stop?

An automobile travelling with speed of 60Km /hr, can brake to stop within a distance of 20m. If the car is going as fast,i.e.120 Km/hr, the stopping distance will be: A) 20m.

Is braking distance affected by speed?

Braking distance depends on how fast a vehicle is travelling before the brakes are applied, and is proportional to the square of the initial speed. This means that even small increases in speed mean significantly longer braking distances.
