Question

Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the instantaneous velocity of car A the instantaneous velocity of car B. Does this mean that car A's acceleration is greater than car B's Explain and use examples.

Answer 1

No, it means car A is going faster than car B. For example, if car A is moving at a constant velocity of 30 m/s and car B is going at a constant velocity of 25 m/s, then the instantaneous velocity is greater.

I think you're over-thinking this. Instantaneous velocity means velocity at a given point in time. Acceleration is the change in velocity with respect to time.

Answer 2

Alright, thanks

Answer 3

Where did this question come from?

Answer 4

uhhh, Physics homework? o.o

Answer 5

@OHHKILLEM I left out the part b/t A & B where the int. velocity increases

Answer 6

... did you copy this guy? http://answers.yahoo.com/question/index?qid=20090827202958AAye8VR
not that I mind...

Answer 7

lol yea he just copy pasted.. but u understand right?

its like saying.. if at any instant the position of A and position of B is given, can u comment on their velocities?

like A is at 5m and B is at 10m.. .. but that doesn't give any information abt how fast their position is changing ergo their velocity..

similarly.. if i say A is going with 5m/s and B is going at 10m/s.. do you think that gives u information about how fast is their velocity changing? (ergo the acceleration)

Answer 8

u have two accounts? :P.. and really isn't it obvious :O :O

Answer 9

oki :P
