Question

A cyclist turns around a curve at 15 miles/hour. If he turns at double the speed, the tendency to overturn is

• A. Doubled
• B. Quadrupled
• C. Halved
• D. Unchanged

Answer 1

Answer: (B)

Quadrupled

Answer 2

$F = \frac{mv^{2}}{r}$ ⇒ $F \propto v^{2}$. If v becomes double then F (tendency to overturn) will become four times.
