A car travelling at 72 km per hour takes a U- turn in 10 sec Find the acceleration?
Assuming the car starts out travelling in one direction at 72mph and 10 seconds later is travelling at 72mph in the oposite direction then we can calculate the average acceleration. First lets reduce the question to SI units. 1mph = 0.44704 m/s so 72mph = 32.187 m/s Since Velocity is a vector quantity (includes direction) the car starts out with a velocity of 32.187 m/s and ends with a velocity of -32.187 m/s. The change in velocity is therfore 64.374 m/s. Acceleration = change in velocity / time taken for change The change is 67.374 over 10 = 6.7373m/s/s. Of course this is only the average acceleration. In reality the acceleration is probably different throughout most of the 10s but we don't have enough information in the question to work out what it is at any given moment. All we are given is the starting and ending conditions and the time between them so we can only calcualate the average over this time.

A motorcycle can accelerate from 0 to 60 in 3 seconds what is its acceleration in miles per hour per second?
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
What is the Acceleration of gravity in mph?
The acceleration of gravity is approximately 32.2 feet per second squared. If you convert this to miles per hour per hour (mph/h), it would be approximately 21.9 mph/h.
What is the acceleration of a car that moves at a steady velocity of 100 kilometers per hour for 100 seconds?
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.
What is an example of acceleration by decreasing speed?
An example of acceleration by decreasing speed is when a car is traveling at 50 miles per hour and then applies the brakes, causing the car to slow down to 30 miles per hour. The decrease in speed over time represents a negative acceleration, or deceleration, as the car is still changing its velocity.
If your speed is 65 miles per hour what is your acceleration?
Well, we know that there are 5,280 feet in one mile and 60 minutes in one hour and 60 seconds in one minute. We can use that and do a little math and find out that at 65 miles per hour you're traveling 343,200 feet per hour. Now we can take that 343,200 and divide by the 60 minutes in the hour and come up with 5,720 feet per minute. Again we can take that and divide by the 60 seconds in one minute to get 95.333333... feet per second.
What is the acceleration of a car traveling from 0 to 60 miles in 4 seconds?
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
How long from buenos aires to montevideo?
It takes around half hour travelling by plane and 3 hours from port to port travelling by ferry.
If it takes 6 hours to drive 432 km how long does it take to drive 72 km?
It takes 1 hour, as the car is travelling at 72km per hour.
What is the maximum acceleration of a train travelling at 90 miles per hour?
The speed or velocity of a train has no bearing on its acceleration.
How long does it take to get from Brisbane to Surfers Paradise by coach?
This journey takes about an hour and fifteen minutes, depending on what time of day one is travelling. It takes longer during peak hour.
How long does it take to travel 22 miles by car travelling 50 miles per hour?
It takes 22/50 hours = 0.44 hour or 26.4 minutes
What is the maximum acceleration of a train with a maximum speed of 90 miles per hour?
You have to know how long it takes to get to 90 mph to solve this. Speed = acceleration x time
If something is travelling at 100km per hour how long does it take to travel 10 km?
It takes 6 minutes.
Which can you find if you know a car travels 30km in 20 minutes?
Either acceleration, average speed, direction, or instantaneous speed.
Travelling at 60 km an hour how long does it take to travel 100km?
60 km an hour is 1 km a minute. Therefore it takes 100 minutes or 1 hour 40 minutes to travel 100 km
If a car traveling 30 miles per hour can stop in 50 feet how many feet will it take the same car to stop when it is travelling 20 miles per hour?
If there is constant acceleration and deceleration then it would be 33.3 ft to stop
Can acceleration be measured in miles per hour?
No. "Miles per hour" is a speed. An acceleration might be "Miles per hour per hour", or "miles per hour squared".
