My Notes O Ast Your 20. O 0.11/0 23 points I Previus Aswers L 2.4.106 The frequency F of a fire truck siren heard by o stationary observer is given below, per second (see figure). (Round your answers to 3 decimal places). where t v represen ts the velocity of the accelerating fire truck in meters 31.300 336 ± v (a) Find the rate of change of F with respect to v when the he truck is approaching at a veloty of 26 meters per second (use- F-26) 1.365 (b) Find the rate of change of F with respect to w when the fire truck is moving away at a velocity of 26 meters per second (use +). F126) Need Help? eashTe

Explanation / Answer

solution-

F=131300/(336+v)

diff wrt v

dF/dv=-131300/(336+v)2

at v=26

dF/dv=-131300/3622 =-1.0019

and sorry i dont know how to solve 2nd question
