okay so I have been given 3 graphs (and equations) for velocity in regard to time. I have then been asked to calculate the greatest speed that each plane attained during the race. What do I do???

Question

If you are in calculus you are take the first derivative test to find the extreme points for each plane and then the second derivative test for the max/min points to see when concave down/up

I am sorry that doesn't make much sense to me. What is the 1st derivative test include?

anonymous · Answer

Ok if this path is not clear... since you have graphs for all three equations cant you read the highest point on each graph? which will be the highest velocity for each plane

anonymous · Answer

yeah I can, but is velocity and speed the same thing?

Velocity is how fast you are going with direction

Speed is how fast you are going without direction

Since you are looking for speed you have to find the point that is the highest or lowest and this number will be how fast you are going (Ignore the - sign because this has to do with direction)

Okay thankyou so much, it is very clear now.
