Final answer:
A stuck gas pedal results in unintended acceleration as the engine continuously receives fuel, increasing the car's speed and potentially leading to dangerous situations.
Step-by-step explanation:
If the gas pedal in a car sticks and the engine continues to receive fuel, the car's velocity will increase as the throttle remains open, causing acceleration. This increase in velocity due to the gas pedal being pushed equals acceleration because the speed of the car is changing. When a car's gas pedal sticks, it poses a dangerous situation, as the car will continue gaining speed until the issue is rectified, potentially leading to a loss of control and an accident. In a scenario where a driver has to measure the distance taken to reach a speed of 60 mph, or the time to come to a stop from 50 mph, the driver exercises deliberate control over the vehicle's acceleration and deceleration functions.
