Question

How fast must an airplane be moving if it makes a turn with a 7200-m radius with a
centripetal acceleration rate of 4.5m/s??

Answer 1

Answer:

180 m/s

Explanation:

The centripetal acceleration a for an object on a circular orbit with radius r and velocity v is given by:

$a=\frac{v^2}{r}$

Solving the equation for velocity:

$v=\sqrt{ar}$
