Problem 3 (10 points). The position of an ant walking along the yaxis as a function of time is given by W) = we +1fi feet. It starts walking at time t = U. (a) (3 points). At what time t 2 [l is the velocity of the ant equal to 1 ft /5? (b) (3 points). If the temperature of each point y on the yaxis is given by the function 1 . 7r T1= 2+sin() (J) 4y 2 3; degrees Fahrenheit, then write down the function that describes the temperature experienced by the ant at each point in time t 2 U. (c) (4 points). Show that at some point in time before I 5 3, the temperature at the ant's position is equal to 19 degrees Fahrenheit
