a police car is searching foe a fugitive taht managed to escape a while ago.knowing that he is now safe,the fugitive begins to take a rest until he notices a police car approaching him at 10m/s,accelerating at 5m/s^2 and it is 100m away.the fugitive grabs a motorcycle and starts it accelerating at the same rate as the police car.how mush time will it take the police car to catch the fugitive?

what is the effect of the height of the track(incline) to the cart's acceleration?may answer is this the effect is that the cart move fast because if the height is higher the higher the acceleration too??i'm right if not ,explain to what is the effect of height..

why is that time is related to the inclnation of the track?please expalin to me

thanks again

since there r many mobile operators, they operate their services on different frequency bands. one company may operate on a higher frequency band and the other may operate on a lower one.

doesn't this frequency difference cause any difference in the quality of connectivity that we get?

if yes, then won't this be an added advantage to the company which operates on a higher frequency?

The problem::
Use implicit differentiation to find the slope and the equation of the tangent line to the curve: sqrt x + sqrt y =9 at the point (16,25)

I dont know how to get the differentiation of sqrt of x and sqrt of y, but i do know that the 9 becomes a 0. Thanks, any help is appreciated.
