Question
Class 3 Examples (ID kinematics) it according to the We he passes the flower Kitty is attracted by the smell of the food in her bowl ond starts accelerating towards it accercenwa flower with equa, on x = (0 50m/r'n' She gobbles her food in ten seconds and then walks back towards he flo figure. constant speed of 050m/s. The initial position of kitty. the flower, and the bowl are indicated on t ated on the figure. on oe going to analyze the motion of kitty from her starting point of motion to the moment the passes her way back (well call this her final position) 5.0 12 x(m) a. How much time takes the kitty to reach her food? How much time takes the kitty her entire trip (from her starting point to the moment she passes the flower on her way back)? b. c. What is kitty's overall displacement for this trip? d. How much distance has she traveled (between her initial and final position) e. What is kitty's average velocity for this trip? f. What is her average speed? g. Find kitty's velocity as a function of time as she speeds up towards her bowl. h. Sketch kitty's position as a function of time on the graph below.Explanation / Answer
(a) Howmuch timet dies the kitty take toreache the food,
x=12 m
= .50*t1^2
t1^2 =12/.50
t1=4.90 s
b. time for food to flow,
t3= d/v =7/.5 =14 seconds
Time for total trip,
t =t1=t2+t3 = 4.9+10+14 =28.9 s
