Answer:
ac = 124.6 m/s²
Explanation:
When an object executes a uniform circular motion, acceleration is produced in it due to a change in its direction during the motion. This acceleration is called the centripetal acceleration. The formula used to find this acceleration is given as follows:
[tex]a_{c} = \frac{v^{2}}{r}\\[/tex]
where,
ac = centripetal acceleration = ?
v = speed = 9 m/s
r = radius = 0.65 m
Therefore,
[tex]a_{c} = \frac{(9\ m/s)^{2}}{0.65\ m}\\[/tex]
ac = 124.6 m/s²
