Formula for the maximum height:
h = v i² / 2 g
If the initial speed is tripled:
h 1 = ( 3 v i )² / 2 g
h 1 = 9 v i² / 2 g = 9 h
Answer:
A ) the maximum height increases by a factor of 9.

Excessive Traffic Delays
While they do help manage the flow of vehicular traffic, one of the other disadvantages of traffic signals is that they can cause traffic delay. Waiting for a traffic light to turn green or waiting for a car in a turn lane to safely cross an intersection can result in long wait periods. Excessive delays can translate to wasted fuel, air pollution and costs to motorists. These are often hidden costs that aren't always apparent to drivers.
Cost of Traffic Signals
One of the other disadvantages of traffic signals is the cost, especially when a less expensive stop sign will do. The cost of installing and maintaining a traffic signal varies, depending on the state. In Missouri, it costs between $100,000 and $150,000 to install and about $4,000 a year to maintain a traffic signal. In Washington, it costs between $250,000 and $500,000 to purchase and install a signal and about $8,000 a year to maintain. A basic stop sign, on the other hand, can average around $400 to manufacture and install. Maintenance costs of a stop sign are significantly lower than a signal, since there is no electrical system to maintain. When they make sense to install, stop signs may be a more viable alternative for keeping city costs down.
Traffic engineers consider the advantages and disadvantages of traffic signals when determining whether to install them. Once they are installed, signals are monitored and adjusted on an ongoing basis to make sure they are as beneficial as possible. If it turns out they are doing more harm then good, the installation of a traffic signal will be reevaluated to make sure it's the best way to go.
