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.)
Can a car have negative velocity and positive acceleration at the same time if traveling on a highway?
Yes.If the car is backing up, but slowing down, then its velocity is in the negative direction, and its acceleration is in the positive direction.
If an object traveling in one direction has a positive velocity what kind of velocity would the same object traveling in the opposite direction have?
Regardless of the direction being travelled, any object on the move has a positive velocity, even if it is moving backwards, because velocity is the measure of the rate of movement in a given direction. Compare: A car is traveling forwards on a highway at 100 km/h. How fast is it travelling? If it turns round (or even it doesn't turn round, but just reverses) and travels at 100 km/h, how fast is it travelling? The answer is 100 km/h in both cases. (But reversing on a highway and travelling at 100 km/h is not recommended!)
Why were they called the 'highway men'?
B/c they robbed people travelling along the highway.
Simpson drives his car with an average velocity of 48 kmh to the east How long will it take him to drive 144 km on straight highway?
144/48 = 3 hours
How did highway men get their name?
They robbed people who were travelling on the highways.
How velocity use in a sentence?
Velocity basically just means speed. We drove at a high velocity down the highway.
How safe is highway 44 and highway 89 in winter when travelling from Reno NV to Portland OR?
Sorry,, not really winter but will be travelling in the middle of March. Are the roads fairly clear of snow by that time of the year ?
When travelling with your family by car are you allowed to pee on the side of the highway?
yes
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 !
Are hybrid cars suitable for highway travel?
No reason why not. So long as they're capable of travelling at the required speed for the road, they can be used on any 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.
