In 20 years, Frank will be half the square of the age he was 4 years ago. How old is Frank now?

A ball is rolling down the slope. It was initially released with a speed of 2 m/s , and it speeds up with a constant acceleration of 4 m/s\(^2 \). The distance in meters that this object travels is \(t\) seconds is given by

\[ d = 2 t^2 + 2 t . \]
