The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.
No. An object traveling at a constant velocity is not accelerating.
Apply to the equation V=U+at . The answer is 40.
Depends entirely on your frame of reference! If you are in a car traveling along side it at 50 ms, the car will appear to be standing still. If you are going the opposite direction at 50 ms, it will appear to be traveling at 100ms.
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!)

yes, the car would have to be traveling at a faster velocity though, assuming that the car weighs less
The wheels only appear to spin backwards.

Speed. (NOT velocity.)
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.

# A car is traveling at a constant velocity with magnitude . At the instant that the car passes a motor cycle officer, the motor cycle accelerates from rest with acceleration . # ## Sketch an graph of the motion of both objects. Show that when the motor cycle overtakes the car, the motorcycle has a speed twice that of the car, no matter what the value of . ## Let be the distance the motorcycle travels before catching up with the car. In terms of , how far has the motorcycle traveled when its velocity equals the velocity of the car?
