Textbook Question
Chapter 5, Problem 7E
Consider a class MotorBoat that represents motorboats. A motorboat has attributes for
- The capacity of the fuel tank
- The amount of fuel in the tank
- The maximum speed of the boat
- The current speed of the boat
- The efficiency of the boat’s motor
- The distance traveled
The class has methods to
- Change the speed of the boat
- Operate the boat for an amount of time at the current speed
- Refuel the boat with some amount of fuel
- Return the amount of fuel in the tank
- Return the distance traveled so far
If the boat has efficiency e, the amount of fuel used when traveling at a speed s for time t is e × s2 × t. The distance traveled in that time is s × t.
- a. Write a method heading for each method.
- b. Write preconditions and postconditions for each method.
- c. Write some Java statements that test the class.
- d. Implement the class.

Consider the figure below, which shows the arrival of 6 messages for transmission at different multiple access wireless nodes at times t=0.1, 1.4, 1.8, 3.2, 3.3, 4.1. Each transmission requires exactly one time unit. 1 t=0.0 2 3 45 t=1.0 t-2.0 t-3.0 6 t=4.0 t-5.0 For the CSMA protocol (without collision detection), indicate which packets are successfully transmitted. You should assume that it takes .2 time units for a signal to propagate from one node to each of the other nodes. You can assume that if a packet experiences a collision or senses the channel busy, then that node will not attempt a retransmission of that packet until sometime after t=5. Hint: consider propagation times carefully here. (Note: You can find more examples of problems similar to this here B.] ☐ U ப 5 - 3 1 4 6 2arrow_forward

Like if I wanted to get a component from wheel from the scene graph, does that require traversing still?
