Fan object moves along the y-axis (marked in feet) so that its position at time x (in seconds) is given by f (x )equals 117 x minus 13 x squared, find the following.

(a) the instantaneous velocity function v equals f prime (x )
(b) the velocity when xequals0 and xequals3 sec
(c) the time(s) when vequals0

117, 9

Step-by-step explanation:

given that an object  moves along the y-axis (marked in feet) so that its position at time x (in seconds) is given by

f (x )equals 117 x minus 13 x squared,

a)Instantaneous velocity function

b) When x=0 we get

feet /sec

c) When v =0 we have

At 9 seconds  velocity will be 0

x = 12

y = 15
