A horizontal curve on a racing track is banked at a $4 5^{\circ}$ angle. When a vehicle goes around this curve at the curve's safe speed (no friction needed to stay on the track), what is its centripetal acceleration?

Options:

Answer:

Solution:

$v^{2} = Rg tan 4 5^{\circ}$

$a_{C} = \frac{v ^{2}}{R} = g$
