Answer: The acceleration towards the center of the circle is approximately 31.583 m/s^2.
Step-by-step explanation:
In circular motion, the centripetal acceleration is the acceleration towards the center of the circle that keeps the object moving in a circular path. The centripetal acceleration (a_c) can be calculated using the following formula:
a_c = (4 * π^2 * r) / T^2
where:
a_c is the centripetal acceleration (in m/s^2).
π (pi) is a mathematical constant approximately equal to 3.14159.
r is the radius of the circle (in meters).
T is the period of revolution (in seconds).
Given that the radius of the circle (r) is 5 m and the period of revolution (T) is 2.5 s, we can calculate the centripetal acceleration as follows:
a_c = (4 * π^2 * 5) / (2.5^2)
a_c = (4 * 3.14159^2 * 5) / 6.25
a_c = (4 * 9.8696 * 5) / 6.25
a_c = (39.4784 * 5) / 6.25
a_c = 197.392 / 6.25
a_c ≈ 31.583 m/s^2
So, the acceleration towards the center of the circle is approximately 31.583 m/s^2.
