Determine the centripetal acceleration of the extreme points of a disk with a radius of 30 cm if it rotates with an angular velocity of 4 rad / s.
Data: R (radius of the rotating disk) = 30 cm (0.3 m); ω (angular velocity of rotation of the disk) = 4 rad / s.
The centripetal acceleration of the extreme points of the disc can be calculated by the formula: an = ω ^ 2 * R.
Let’s make a calculation: an = 4 ^ 2 * 0.3 = 16 * 0.3 = 4.8 m / s2.
Answer: The sought centripetal acceleration of the extreme points of the disk is 4.8 m / s2.
