If A car travels down the highway at 55 mph its speed is what and its acceleration is what?
Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.
A truck is traveling east on a highway at 80 km h What is velocity?
Velocity is speed and direction. Truck speed is 80 km/hr. Truck velocity is 80 km/hr going east. Its velocity is also -80 km/h going west, and 0 km/h going north or south.
Which is the best estimate of the length of a car?
The UK Highway Code in discussing emergency stopping distances uses the average length of a car as about 4 m or 13 ft.
191 km is how many hours travel?
That would depend on how fast you are traveling.At an average highway speed of about 100km/hr it would take a little less than 2 hours.
Which of these would you use meters to measure hallway highway or pencil?
a hallway
If Simpson drives his car with an average velocity of 85 kilometers per hour eastward How long will it take him to drive 560 kilometers on a perfectly straight highway?
Just over six and a half hours... D'oh !
What is the net force acting if your professor's car is traveling west with a constant velocity of 55 mi-hr west on a straight highway?
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
A toy car travelling along on a straight highway is showing a negative change in velocity?
if it slows down or reverses direction.
How velocity use in a sentence?
Velocity basically just means speed. We drove at a high velocity down the highway.
What is the velocitydistancespeed and displacement about this problem a car is moving to the north along to a straight highway and stops after 1 hour for refueling at a gasoline station 80 km?
Velocity: average of 80 km per hour due North, 0 when at station. Distance: 80 km. Speed : average of 80 km per hour, 0 when at station. Displacement: 80 km.
How does average velocity differ from instsntaneous velocity?
If a 5 mile stretch of a bus journey lasts 15 minutes, then the average speed over this stretch was 20mph. But undoubtedly the bus achieved greater speeds than this, and it also spent time sitting still in queues. So the simple answer to the question is 'yes'. Less trivially and more interestingly: unless velocity is actually constant, then an object's average velocity over a finite time interval - and hence any empirical measurement of its speed - must (nearly always) differ from the instantaneous velocity. As the time period grow closer to zero, the measured velocity will converge on the instantaneous figure, but will never reach it.
What was the total cost of the national road?
$500,000,000 for the average highway. $500,000,000 for the average highway.
Diffrence between velocity and acceleration?
Velocity is the constant distance that is traveled by a body per unit of time. Acceleration is the rate at which the velocity can change. On a straight highway, you put your car under cruise at 65mph. The car travels (except for the imperfections on the road) at this constant speed. The speedometer stays almost at 65. That is as close an example I can give you for velocity. On the other hand you enter a highway from a ramp, you usually press on the accelerator hard to gain speed to merge into fast moving traffic. The speedometer rapidly changes from say 10mph to 20mph to 23 mph.... and so on and this is acceleration.
What are most dangerous areas of the highway?
Curves with hills, especially after a long straight part of the highway.
What is an example where speed becomes constant but velocity changes?
Taking a turn on the highway.
What is Australia's longest straight road?
Highway 1, east of Balladonia -- 90 miles of straight road
Can an object accelerate and have zero velocity?
I'm not a scientist, but the following seems reasonable to me. If your frame of reference is the earth's surface, then it seems clear that an object can have zero velocity and zero acceleration. You could even have non-zero velocity and zero acceleration. What seems impossible is to have zero velocity and non-zero acceleration. When you think of accelaration think of changing velocity. A car moving straight down the highway at a constant speed of 55 mph is neither speeding up nor slowing down. Though it has velocity, there is no change in its velocity so acceleration will be zero. For a car parked on the side of the road, on the other hand, its velocity will be zero but what about its acceleration? Is velocity changing? No, so it will have zero velocity and zero acceleration.Yes.
