What is the final velocity of the truck at 90 km/h?

So, 90 km/h= 90×5/18m/s = 25m/s. This is the initial velocity of the truck and final velocity is zero. Futher on, we can apply third equation of motion here but sign of acceleration will be negative because it is retardation.

How far did the car travel after the brakes were applied?

The car traveled 125 meters after the brakes are applied. With linear deceleration from 90-0, the distance would be exactly half what it would have travelled at 90km/hr, which is (on average) 45km/hr for 10 seconds. 10 sec. divided by 3600 sec/hr multiplied by 45,000 meters = 125 meters.

What is the minimum stopping distance of the same car?

A car moving with a speed of 50 km h −1 can be stopped by brakes after atleast 6 m. If the same car is moving at a speed of 100 km h −1 the minimum stopping distance is : The Fish Tale Across the Wall Tenths and HundredthsParts and Whole Can you see the Pattern?

What is the retardation of 126 kmph on a straight road?

Originally Answered: A car moving along straight road with a speed of 126 kmph is brought to rest within a distance of 200 m. What is the retardation and time? First convert 126kmph to m/s ie. 35 m/s.

What is the retardation of a car at 72 km/h?

A car is moving at a rate of 72km/h and applies brakes which provide a retardation of 5ms-2. How much time does the car take to stop? You need to convert first 72 km/h to m/s.

What is the speed limit in a school zone?

The speed limit in a school zone is 40km/h. A driver traveling at this speed sees a child run into the road 13m ahead of his car. He applies the breaks, and the car decelerates at uniform rate of 0.8m/s². If the driver’s reaction A car traveling 95 km/h strikes a tree.

How do you calculate acceleration from initial speed and final speed?

The acceleration of the car is solved by subtracting the initial speed from the final speed then dividing the result by the elapsed time. The 4 Worst Blood Pressure Drugs.
