To find:
a. Parametric equations that model the motions of the bus and Jodi as a function of time. [Hint: The position s at time of an object having acceleration as is ].
Answer to Problem 52AYU
a. ,
Explanation of Solution
Given:
Jodi’s bus leaves at 5:30 pm and accelerates at the rate of 3 meters per second per second. Jodi, who can run 5 meters per second, arrives at the bus station 2 seconds after the bus has left and runs for the bus.
Formula used:
Calculation:
Let be bus’s path and be Jodi’s path.
a. Bus:
Jodi:
To find:
b. Algebraically whether Jodi will catch the bus. If so, when?
Answer to Problem 52AYU
b. No, Jodi cannot catch the bus.
Explanation of Solution
Given:
Jodi’s bus leaves at 5:30 pm and accelerates at the rate of 3 meters per second per second. Jodi, who can run 5 meters per second, arrives at the bus station 2 seconds after the bus has left and runs for the bus.
Formula used:
Calculation:
Let be bus’s path and be Jodi’s path.
b.Bill will catch the train only when
does not have any real function as
Hence Jodi cannot catch the Bus.
To find:
c. Simulate the motion of the bus and Jodi by simultaneously graphing the equations found in part (a).
