Question

Assuming a Chevy Cruze may be operated indefinitely at 30 m/s with no stops for provisions,

and may be refueled in transit, how long (in years) would be required for the Chevy
vehicle to travel one light year?

A. 1,000 years
B. 100,000 years
C. 1,000,000 years
D. 10,000,000 years

Answer 1

To solve this problem we will apply the linear motion kinematic equations. In which the speed is defined as the distance traveled in a certain period of time. In turn we must emphasize that 1 light year is equivalent to
`9.461*10^(15)m`. Mathematically the speed is described as,

`v = (x)/(t) \rightarrow t = (x)/(v)`

Replacing,

`t = (9.461*10^(15))/(30)`

`t = 3.15366*10^(14)s ((1 year)/(3.154*10^7))`

`t \approx 10,000,000 years`

Therefore the correct answer is D.
